Thanks for replying windsor4fun2. I've heard rumours that it's actually allowed if it's not in the common areas. I decided to make a phone call and emailed cherry lane resort. Here is the answer:
"Open sex in common areas such as the pool, club house, etc. is not allowed. However we have 80 acres and a place called "fantasy land" where I'm sure you can find a place for outdoor fun."
I guess we will visit the resort soon!!!
