Highly recommend H2, it's a really fun, safe environment. The rules are "no public sex" and we saw that the staff ALWAYS made their way towards public sex acts to break them up, just a little to late. Met one guy there who took his wife there every year on vacation so he could get a break - he told us this in the hot tub, while his wife was laying on a table near the swim up bar being eaten out by two girls and one guy.
If you enter the grotto, you are pretty much fair game. LOL, so definately go in there.
The crowd varies, but twice a year they have wet, wild & wicked week; swingers groups book most of the place, but there are always a few rooms left, try booking during one of those weeks.
Last time we went, stayed 10 days!
We'll be back.
