Thanks Scubadada! I assume the east end is a better choice for early December? I have never driven on the "wrong" side of the road and am a little concerned on that...
I have never stayed at CCGCR but we visited and dived with them one day last October and it seemed like a nice place and a good dive op but we haven't eaten there. The winds and the waves were high up there that day and there wasn't any shore diving. We had to take the van to the marina to dive the West Side. We talked to some folks that were staying at the resort and they were disappointed because they hadn't been able to dive the North Wall or shore dive at the resort all week because of the weather. But bad weather can hit you anywhere at any time.
There is good diving on the West Side but if you are used to Bloody Bay Wall then you may be disappointed, the North Wall and East End are our favorites areas to dive on GC and we enjoy some of the snorkeling and shore dives on the west side. The CCGCR is well positioned to dive the North Wall as long as the weather cooperates.
If you stay at CCGCR I still think you need a car, the resort is located far off the beaten path and there is a lot to see and do on GC.
If you are stay on the East End at Compass Point, you will need a car but the local driving will be pretty easy because you will be far away from the more popular areas - but you will have to drive through those busier areas to get there and back. I am not a big fan of driving on the left and negotiating the roundabouts, but my husband actually enjoys it! You'll get used to it and we have found it helpful to bring a GPS and car charger with us to help us navigate. Plan to arrive during the day or afternoon because you don't want your first time driving on the left to be at night in the dark.
Sunset House is south of George Town and they have an onsite dive op and shore diving and breakfast is included but you will have to eat out for other meals - and that can get pricey. But you are close to the restaurants and shops and can take cabs or the bus and there are many fine restaurants on GC. Sunset House mostly dives the West Side and it isn't in the same class as LC in my opinion.
If you want to go back to Cayman but would like to try something new then I also suggest the CBBR. It was recently renovated and has a gorgeous pool and the food is better than LCBR in my opinion. It is very similar to LCBR and the island is also undeveloped and rural like LC. The diving is very good and you can take a jet to and from CB if you would rather not deal with the twin otter planes.
And if you can add a few days to your trip, why not spend a little time on GC before heading over to one of the sister islands? That's what we like to do!
