Expect nothing but prepare for everything. My boyfriend expected to go naked most days but once there realized it was much more comfortable (= less hot) for the skin to have just a simple layer to cover the sun's rays. Luckily he had brought sarong just in case
Edit to add: very few will judge you or care if your beautiful self goes around naked and those few are assholes anyway so nobody cares what they think
Just make sure you try to be cognizant of areas like Kidsville and respect others desire for no nudity space.
