You will lose to much time getting to "GC"!! Even with being a single ship, it gets tight getting around and having to be back before she leaves without you. I would say IMHO. Rent a car, go to Orient village for lovely places to eat and throw some towels down on the beach and take it all in. The beach is over 2.5 miles. it's not a hiking, but a beautiful walk!! My BIG recommendation for car rental would be SAX car rental. The service is amazing!! Rates are very competitive! Lovely people to do business with! Cindy and her husband are lovely people!! It just looks like you'll have to book your dream vacation for a week or better to do all the things on your list! Have a great trip! https://www.saxcarrental.com/
