I was just at Tropicana last weekend and the pool is very much full despite it being February. That said, I have no earthly idea if it was heated. I am a relative local, so there is just no way I am going swimming in less than 80 degree weather so I didn't even try You can always call and ask. I found the staff very friendly. They do have a jacuzzi also.
The Park Vue Inn has a heated pool. We were there Jan 31-Feb 11 and the kids and I were in it every other day or so. I do have to say though, that in the evenings, even though it was heated it was a little chilly, though nothing compared to how cold you get when you get out lol.
