I'ts been a few years since we have been to Hedo... and only was there twice. But I will echo all that gredandkelly said. You would honestly feel a bit out of place fully clothed there. Nudity is the norm, and once we dropped our clothes, we felt more comfortable.
You WILL see sex on the beach, sex on the lounge chair, etc. so there's a heads-up on that front!
It's a fun place but you don't have to feel pressured into doing anything you don't want... a polite 'no thankyou' to any invitations is all it takes.
We thought of getting a day-pass this coming vacation, so it was good to learn the new prices.
