We are going to Hedo, the end of April. It's our 28th time there. Hedo attracts a mature party crowd. You will fit right in. As far as guys, I'm not sure if there staff is still playing around. The new owners maybe a little more restrictive? There are usually good in the hot tub at night.
It kind of depends on your expectations. I had one female friend who was probably close to 70 who went to Hedo with a boyfriend. She had a goal of fucking 3 guys every day she was there. She was seriously not happy, because on 2 days she only had 2 guys!
