"Nice hotel, expensive stay-in"
Very nice hotel, very nice facilities, welcoming and friendly staff, clean and neat. The park is huge, we loved it, kids loved it the most, spending the whole day in the park, with lots of activities.. Some activities are very expensive and i believe they're not worth it at this rate (photos with the dolphins or sea lions), for example, 10mins photo session for each person is $170, so for a family of four you're looking to pay $680 for 10mins.! Some photo sessions goes up to $320 per person for 30mins.
Food is expensive (because that's whats available to you from the hotel anyways) drinking water is free in the room, use that!!, there is no supermarket in the palm, so u either buy from the resturants available to you, or take a trip to the nearest supermarket to pickup grocery and food for the whole day. A taxi to Mall of the Emirates would cost around $15 for a one way trip.
Always go with the government taxi (beige/blue or beige/orange) because they run a meter and will charge u based on that, and its always the cheapest option. Otherwise, you pick from limo to luxury cars, but its always expensive.
All in all, great experience.. I would definitely go again, but i will not stay in, and will make sure i take my food with me.
