we were there last weekend. the park gets busy by noon so it is better to do the rides right away.
if you have small kids, get the life jacket right away to avoid line ups. Most of the rides, small kids can ride with an adult but they have to wear a life jacket. My 6 year old rode almost all the rides except the fast tracker/vertigo as they have height restriction.
the water is also heated so even if the weather if gloomy, u can warm up in the jungle river or wave pool
