I've not been to any of the pools downtown. You can also go to strip hotel pools that might have more "scenery" if that is what you are looking for. (As a newly single male in your 30s). There's totally crazy pool party/day club pools. But also some "standard" pools that are pretty fun. The Wynn European pool (adults only. Topless optional but most keep their tops on) is a really good, non-dayclub spot.
