just to add to what has already been said. THere are tons of chairs and the guys who work there will gladly carry a chair for you to where ever you want I TIP them 1-2 $$
You need a hut if you cant sit in the sun or you want to nap (dont fall asleep for hours with no sunscreen!!) There is always shade at the pool for an afternoon kink. LOL NO waiting for chairs and you really dont need a palapa (umbrella) for all day just the hottest 12-3 good luck!
