There are public bathrooms at Papagayo and at the Perch. The Perch is open through the vacation closing of Club O. Papagayo is not open right now, can't remember exactly when Club O reopens, but the bathrooms there will be open once Papagayo's is open. I don't know if the bathrooms by the guard shack at Club O are open right now or not. I assume that the PAY bathrooms behind Pedro's are open right now, although I don't know for sure. The construction does not involve Pedro's, so Pedro's is open through the construction, so I assume the bathrooms are open, but don't know. Otherwise, once you get past the construction area, Kontiki and all the restaurants past that all have bathrooms and frankly no one is going to ask you if you're eating there to use those bathrooms. Pinel, I don't know, haven't been there in forever..
