We have visited Catalina as a port stop, day trip, and also a long weekend at a hotel. The golf cart is fun just make sure you have your DL and proof of insurance. CA DMV considers them motor vehicles so you will need both. You can't just go anywhere you want as they are restricted to specific roads. But still plenty of fun. You will return it with plenty of time to walk around Avalon and grab a drink or food. We also did the "submarine" which was interesting.
