There was a time, a few years ago, when the beach house pool was constantly out of towels. This was when the resort GM still met with members following the "Behind the Ears" tour, and someone took that opportunity to ask him about that problem.
He said that a lot of it was due to people bringing the pool towels down to the beach and leaving them there. I don't remember the exact numbers, but he did say that they lost a LOT of them each day. Guess where the money to replace those towels comes from?????
Anyhow, as been mentioned, the towels are not really "beach" sized. We always bring a blanket to stretch out on (unless we have our beach chairs) and a regular beach towel to dry off with.
