Even if it is quite expensive, it is worth to spend a day there. Take the platinum package which is 325 Dhs per person, but you´ll get a towel, a locker a meal including drink and a souvenir cup which can be refilled for 5Dhs instead of 15 Dhs! You will find discount booklets at every hotel that save 40 Dhs per person! The park is amazingly designed, palmtrees all over the place, grassland next to the beach and a lot of sun loungers around. Nevertheless it was quite difficult to find an empty spot for 4 persons. The slides are great, a very steep one, tube roller coaster and a lazy river which isn´t that lazy, including rafting, the ride around the park takes about 30 minutes and is a lot of fun. Single and double tube rides, a kids playground, slides that take you through the shark tank and direct beach access with beach volley ball and beach soccer field. Definitely a great place to have fun in Dubai.
