are the rooms entered from the outside?

Most of them, yes. The ones that enter from the inside are the ones that make up the courtyard that surrounds the indoor pool and are more expensive.

I've stayed in both.... inside rooms near pool are usually more costly.

Yes and no. I have stayed in both at this location.

There are 2 buildings, main one with the pool and restaurant/bar, which has both inside atrium and outside doors; back behind that, all outside entrance rooms. For events and reunions, I prefer the atrium rooms for the attendees, and I usually book an outside room for "running away from chaos" LOL

Yes
