Dubai Mall - Aquarium and Dubai zoo upstairs, boat trip on top of the aquarium.
Kidzania at Dubai mall - a whole world for kids, where they can work in the bank, a a dentist, make a real MacDonald's themselves, make perfume, coke factory, deliver parcels, earn money, work at Waitrose. truly amazing and my dd 8 spends hours upon hours in there!! Then Rainforest café for meal ( no alcohol served here!!!)
Mall of the emirates - Ski Dubai and magic planet full of games and rides
madinat - great hotel and lots for kids to do
Wild wadi water park at the Jumeriah Beach Hotel is definitely better than Atlantis, Atlantis is not geared for little ones as they can hardly go on any of the rides due to height restrictions.
Go to a Friday brunch!!! Dubai must!!! 4 hours of non stop champagne and any other drink u want and every type of food u can possibly imagine( seafood, sushi, pasta stations, satay stations, paella, every meat imaginable cooked to order, kitchens u can walk in and they make anything u want, roast of every kind, tapas, cheese rooms!!!!!!!! magicians coming round doing table magic, acrobats, petting zoos, kids entertainers and 4 hours of drink and best food ever!!!!!
Best ones are the Al quasr, Mina a Salam or bubbalicious at the westin!
approx. £80-90 per adult and half for kids but well worth it.
Dubai has thousands of amazing resturants, so don't restrict yourself to the Atlantis!
Frankies at JBR is amazing ( Frankie detorris and Marco pieree whites )
Ruth Chris Steak House at the Address Marina hotel
Gary Rhodes at the Grovesnor hotel
Grand grill at the Habtoor grand
The beach bar and grill at the One and Only Royal mirage
Benihassi tepenyaki ans the Rotana at JBR
Oh and always ask for local taxis at the hotel if going out (they will be cream with colured roof) as they will try and put you in a 'hotel' taxi and u will be charged anout 4 times as much!!! taxis are cheap as chips and plentiful !
