I really enjoyed my time at the Mirage pool.
I know that some people have said that they have anxiety regarding whether they can sit at the pool and be comfortable despite their body type. I was here on a holiday weekend (Labor Day) and saw people of all shapes, ages, etc sitting by the pool.
I also want to add: I LOVED THAT people that would not typically wear bikinis were. So awesome. My only piece of advice would be to get down there early if you want to be poolside for most of the day. Chairs were taken by 9 and not available until 5.
