I'd use the word "cabanas" loosely to describe the three covered structures at the new Oasis Pool. These are not cabanas in the traditional sense, meaning there are no sides, privacy, TVs, or other amenities. Just plush couch-like seating and a roof. They are nice and big though, can seat a large family. They are first come, first served and are pretty coveted spots for sure. We were there last week and it seemed most mornings they were taken pretty early after opening (7AM). We managed to get one our arrival Saturday at 2:30ish when someone finally left (which was a blessing because it was sunny as all heck).
The Lava Pool used to have more traditional cabanas prior to the renovation but those aren't there anymore.
Sorry if the above is obvious info, just want to make sure it's clear what is there.
