Ok...well will start from beginning. Currently there is going A dubai duty free tennis tournament, which attracts lots of attention (however , i believe, is going to end in the next couple of days). Nex, Bryan Adams is comming on 14th of March to perform (tickets is 195Dhs- around 70$) For performances and concerts- that is it actually...
Dubai I guess is a leader in amount of shopping destinations you can get. However, they all ressemble each other (the most popular- Mall of Emirates, Ibn Battutta, City Center, Mercato Mall, Burjuman Centre)...Discounts vary, however, now it is not a season for discounts, surely there are shops which have some.
In case you are willing to purchase any electronics- laptop, mobile phone etc. please pass by Carrefour- all in one supermarket located in Emirates mall and City Center, where you can get same phones and pcs for almost half a price, rather then bying them from freestanding electronic shops.
Take a tour on the bus around dubai (it will cost around 120Dhs- 30$)...go to the beach. Wild wadi is good choice, although again- pretty expensive 150Dhs- 45$).
Burj al arab - 7* hotel- landmark of Dubai- are charging for entrance- 200Dhs ..so i m not quite sure, if it is the right choise for you, unless you really desperate to see from inside this hotel (from personal experience, I will tell you- it is not worth it!)...
Zoo is small and borring..., and Planet Hollywood is basically a nightclub and restaurant...Nothing much to do either.
The rest is pretty ok...Enjoy your vacation in Dubai!
Oh, almost forgot, the best dining places are always located in 5* hotels. So please, if you would like to experience some incredible cuisines and service, visit The Fairmont's _ Spectrum On One (multiethnic cuisine), The Exchange grill (fine dining), Finz (Ibn Battuta) or one of Madinat Jumeirah restaurants. You will be wowed!
Bon Voyage!
