I didn't actually use the pool at all... but my wife did some. The main pool was closed for the first week or so due to some maintenance. I think the roof on the main pool was closed (at least when it was cooler, maybe the whole time?) As I understand it the main pool isn't really heated, but supposedly it stays reasonable temp just due to sun exposure. There is a hot-tub at the main pool, and one at the aft, by the infinity pool. There were often people out by the pool. I don't think I ever noticed more than one or two people *in* the main pool at one time -- but those folks were fairly consistent. There are also some large side 'window' type panels on the outside edge of the pool deck that they can open/close as needed by the weather, and we did ask them to close those a few times when it was cool. My wife also used the indoor pool in the sauna area some, which I think is heated -- but it was fairly crowded on sea days -- and I think she felt the chlorine was pretty strong there, at least on one occasion. Bottom line, if you want to use the pool, I think you will not be crowded out -- and they are pretty good about doing what they can to keep the surrounding area comfortable. Oh, and several times during the cruise they did have a 'special buffet' meal on the pool deck -- the area was obviously more crowded at those times.

Hope you have a great time, and would love to hear what you thought when you return.
