I've skated twice at the Clearwater Ice Arena (up the street from the airport, on Icot Blvd). Both times (once early morning and once late in the afternoon) on lightly populated publics while I was down in St. Pete for a sailboat regatta. Can't really comment on whether or not it's adult friendly. I had no problems. At one point the rink was undergoing major structural renovations and because of that getting into the building's lobby was a PITA but I suspect that's finished by now. I don't take my skates traveling anymore 'cause my wife doesn't like the prospect of driving a 1000 miles home, towing a boat trailer, if I fall and break something!
