My wife and I are thinking of laying over in PR for three/four days on the way to some other islands. I'm thinking it might be nice to rent scooters, possibly bikes. Anybody know the area, and have rental suggestions and where to ride? I figure if I get local advice I'm in better shape than goping in green. While I'm at it, are there any hostels (or other cheap digs) on the island we can check out?
