Yes, why not taking advantage of Dubai perfect geo-centrality and of course of its excellent airlines/airport connections and combine two visits in one ?
I have three or maybe four possible and equally fascinating alternatives for you :
Dubai and Seychelles
3-4 days in Dubai and 4-5 in Seychelles I believe is the most logical plan. With flights departing from Dubai Airport for Mahe/Victoria at night and arriving at destinations early morning in little more than 4 hours you can even save a lot of time. An ideal combination from my point of view as Dubai and the UAE in general are a place to be lived actively and where time should be spent visiting the thousands of attractions and not on the beach. Few days of full immersion to see the world biggest mosque, the largest shopping malls, the tallest tower, the only Ferrari World Park, the incredible Atlantis, the breathtaking Burj Al Arab and of course to enjoy the best Arabian hospitality.
Total relaxation is next, in one of earth last paradises. Mahe, Praslin, La Digue and even more secluded and totally isolated islands await you with their typical African and creole atmosphere, their fantastic white sand beaches and crystalline clear waters. Four to five days are more than enough for some unforgettable boat excursions to Coco, La Digue and Curieuse, Cousine and Cousin islands. Have fun diving or snorkeling in some of the best deep-waters anywhere. Not only will you swim with massive and gorgeous tropical fish, but you’ll also spot white tip reef sharks, gray stingrays, turtles and many more creatures.
Dubai and Oman
What a fantastic way to continue a journey of discovery of the Arabian Peninsula. After the grandeur of Dubai with all its fascinating modern developments, the chance to visit The Sultanate of Oman, Middle East’s best kept secret and a country with an enormous wealth of natural attractions, fascinating culture and history dating back to as far as 13,000 B.C., stunning landscape and warm welcoming people.
Over 500 forts, castles and towers in diverse architectural styles, stunning deserts, wadis and underground caves, fascinating souks, wildlife, pristine waters and rocky mountains make of Oman the ideal destinations for the demanding cultural tourists as well as for the nature enthusiasts. The Omani people are renowned for their good manners, so wherever you chose to go, you will sense an air of hospitality and genuine friendliness.
Dubai and Golden Triangle India
India and the UAE enjoy a very strong bonding which is founded on millennia-old cultural, religious and economic intercourse between the two regions. People-to-people contacts and barter trade between the two regions existed for centuries. For these reasons, I believe it is worth continuing a tour to India after visiting Dubai.
The Golden Triangle is probably India most visited area by tourists from all over the world. Delhi, Agra and Jaipur have some of the greatest representations of the influences India has seen from the ancient Mughal and Rajput empires to the British colonial legacy and the vibrant life of modern India : a magic combination of contrasting experiences and unforgettable visions of architectural creations, exquisite crafts and a wide range of fine, folk and performing arts.
In less than three hours flight from Dubai, you will embark in a journey that brings in much more than you could have imagined and offers you plenty more than just the Taj Mahal, making every moment worth the while, and every penny well spent.
Dubai and Iran
Travelers who have an appreciation of history, art and architecture will find Iran an amazing country where stunning architecture and hospitable people complement each other to create an exciting experience for tourists. Legendary treasures will unveil in front of your very eyes like Shiraz, Esfahan, Kashan, Yazd and why not even Tehran, the capital, which showcases how Iran has leaped from its ancient history, through its line of art galleries, coffee shops, restaurants and the merry mix of residents.
Majestic mosques, breathtaking monuments and mausoleums, magnificent ruins of ancient cities, but also a very generous and rich nature. Here you will experience different cultures and religions, with a hospitability you have never seen before.
Beach and Swimming. Despite the heat, Dubai and the rest of the UAE beach temperatures are often tempered a little by gentle coastal breezes. The water is quite warm but frankly I prefer this temperature to the cold one of the Ocean or even of the Mediterranean sea, let alone that of lakes, especially those in the mountain.
Golf. There are eight green 18 hole golf courses including 2 championship courses, and all of them offer 50% discount on the normal fee rates. Starting at 8.00 in the morning or 4.00 in the afternoon and driving up and down with a very comfy buggy makes the heat very bearable. On top of that the unique scenarios of almost empty courses, no rush or pressure all of which leaves you plenty of time to concentrate on your shots and to admire the beauty of the golf courses and their surroundings.
Water parks. Dubai and the other Emirates have many water theme parks with rides and games that can be enjoyable to kids and families. Wild Wadi, Aquaventure, Dream Land are some of the largest water parks in all the Midlle East, with state of the art technologies, safety features and facilities. Some of these parks like Wild Wadi and Aquaventure are directly connected to big Hotels which adds extra comfort in terms of logistics.
Shopping. Even in winter shopping in Dubai means air conditioned malls so no big difference in summer. Malls are open from 9.00 or 10.00 in the morning until 10pm or later and all as I said earlier have air-conditioning, which makes for a great escape from the summer heat. The retail mix is amazing with an unbeatable combination of local, regional, European, North and South American as well as Asian brands ! Summer sales and promotions are even more attractive than those in Europe with excellent opportunities for real bargains in all retail segments: fashion and cosmetics, home accessories and furniture, electronics and appliances and much more.
Ski Dubai. More action and entertainment available at other uniquely exciting places like Ski Dubai, the breathtaking indoor skiing complex, the Dubai Mall mega aquarium and its Atlantis Hotel version which includes also a full fledge dolphinarium with lost of shows and interacting sessions. 
Kidzania. Last but not least a truly unique and unforgettable experience for children (and their families too) aged 2 through 14. Built on a 5.000 square meters indoor area and themed as a child-sized replica of a real city, Kidzania features buildings, shops, theaters, police and fire brigades stations as well as vehicles and pedestrians moving along its streets. In this city, children work in branded activities from bottling local produced milk to working in a tooth paste sponsored dentist office or serving food at a famous restaurant chain and many more activities (more than 70). Children earn KidZos currency while performing the tasks, and the money is kept in the KidZania bank for them to spend at the gift shop and on non-free KidZania activities.
