Chair tag issue--easily solved by a sign on the beach like all the chair places on the other side of Pedro's. "Price for a chair and 2 umbrellas, a guard will find you for payment. Do not use or move chairs with plastic dated tags." There's some reluctance to post rules, info, etc. for non-guests, but there are plenty of signs for other things. Also a sign somewhere easy to find with sports rental prices might increase the use of the boats and stuff.
Last comment, a sign with "Nudist rules'' at the Perch or somewhere would be useful--sit on a towel or put something between you and chairs, no sexual activity, etc..." I've seen a lot of unusual and inappropriate stuff on the beach and in the restaurant, especially in the last year or so.
