Maybe because only about half the couples who go are swingers? I saw plenty and we put on our own but we aren’t swingers.
if you want to see shows, book towards the ends of the tower. we were next to the jacuzzi center rooms of the tower and everyone could see us on the bed. i think 2 rooms could even see us in the shower. we left the shade open the whole time. we didn't have a view into any of the rooms from there. if you book higher up, you see more on the balconies as well
