Hi sis. I went to Dubai early this year and I had a blast! Stayed at The Palace Old Town and the area around the hotel was awesome. There's Burj Khalifa nearby, an obvious must see, Dubai Mall for high end shopping (highly recommend dining al fresco at Wafi Gourmet with the views of Dubai fountain), doing the hop on/off tour so you can get a glimpse of the city. I enjoed the 4x4 desert safari tour also, transport,BBQ dinner and show included, found this to be really good value. I've been to the Atlantis Bahamas already so had to skip the one in Dubai but I'm sure it's as impressive, if not more. I also recommend trying flavored houkkah/sisha, while having mezze and cocktails (something you can do at night). Or you can opt to have a nice meal or drink at the Burj Al Arab,take note though that you need to make a reservation in advance!
Didnt shop much since everything is cheaper here in the US. Although I highly suggest buying assorted baklava/sweets from Wafi Gourmet, a bit pricey but so worth it. I was hoping to buy gold jewelry but was unsuccessful. The prices were beyond what I had in mind.
Hope this help
