I spent a week on Grand Cayman and we wented a car, other than driving on the "wrong" side of the road, there is no reason why you couldn't rent a see the island on your own. From what I can remember there is one road the goes around the perimeter of the island and one the cuts through the middle. When we were there we stayed at the opposite end of Georgetown at a reosrt called Morritts Tortuga Club and it was beautiful! I would love to go back someday!!! There is an area on the south end about halfway between Georgetown and the other end of the island(I believe it is called West End) where thereis a small beach and an beach phenonmena known as the "Blow Holes". This is where the water crashes through thes holes in the rock formations and they look like little geysers. When we were there, the beach wasn't crowded but the coast was pretty rock so swimming would be difficult.
THe entire island is beautiful and you can make a com[plete journey around it in about 3 hours(maybe less)...its been about 5 years since I was there but from my recollection there sre distinct areas, like the west end is rocky and the island justy sort of drops off into the ocean whereas the eastend has the beautiful beaches(7 mile beach) If you take the road that cuts up the middle of the island there is a Botanical Garden which was beautiful, if you are into that kind of thing.
Also, in the north there is a place called Rum Pointe that has a hotel and some restaurants.
Don't forget about Stingray City...that is a marvelous place...like nothing I have experienced. There are companies in Georgetown that offer excursions there. The one is Capt. Marvins and the [people on this board have given them positive reviews. I can't remember who we used but it was also great!!
There is also a store and gallery run by a womand named Cathy Church about 1 mile outside of Georgetown. Cathy takes underwate photography and her pictures are amazing!! Her website is
www.cathychurch.com(i think). We found out while there that she is from Altoona, PA where my BIL grew up so that was kind of cool!
The turtle farm is great and Hell is unique! The good thing about Grand Cayman is that the island is relatively small so you could drive the whole thing in a day and see alot of the sites. I loved driving around because some of the houses that are there are absolutely gorgeous. There is ALOT of wealthy people there and the houses show it.
The other thing I found was that the island was pricey! When I was there the exchange rate was $1.25 Cayman per $1 US...so everything was 25% higher and they have to import pretty much everything so prices are higher.
Oh yeah, don't forget the Tortuga Rum Cakes and Stingray Beer. I think they are the only things that are produced on the island(LOL) but the cakes are good!
Depending on when you are going iot might be really HOT! I was there in August and the humidity was a killer!!!
As for renting the car, we had a Nissan Sentra and that was pretty much what we saw on the road, little cars and I don't remember there being a lot of traffic(nor alot of roads)
I still have all the stuff somewhere so if you want more info, let me know.
PS-The island has no povery or unemployment so crime isn't a concern..At least it wasn't 5 years ago. I hope it hasn't changed!!
