Tikiman mentions:
The Lava pool during the summer is open 9 A.M to 11 P.M. During the colder months is was open 10 A.M. to 8 P.M.
(But I don't recall the lava pool being open that late over the summer)
The Oasis pool seemed to be open later, but there was Aparantly a glitch in the gate locks that has since been remedied.
