I think Rick's is a hoot watching people jump and the pro divers too. We stay a few hours and watch the sunset and then walk (or a very short cab ride) down to Seastar for the Saturday concert. Seastar will then take you back to your hotel for no charge after the buffet\concert.
Mayfiled Falls in not for the disabled.
I'm alwys a proponent of going to Sav early on Friday or Saturday to check out the market. Of course "early" might not be helpful if you are out late partying the night before!
