Just like other resorts in South East Asia (e.g. Thailand, Vietnam), you get everything you need when you staying in here. Everything in a cozy settings to make you relax. What's more, in Lapita, you have got more theme parks, and a very nice walkable area (the european feel villages) and a outlet nearby in walking distance.
However, it is quite remote to outside areas, and the transportation cost is quite expensive in Dubai, i will suggest to stay and enjoy the relaxation within the resort during your stay.
And as i travelled in October, it is still very hot under the sun, everyday after 4pm, is the best time to enjoy your pool time and outdoor activities.
All in all, is a kids paradise! It is a perfect place to travel with kids!
