I was there in Morritts Grand sometime back and I should say it was fun. There are a number of timeshares available at Grand Cayman, and I believe all of them are good. I stayed in Morrits Grand and it was in excellent condition.
Our room was really good; had a balcony with oceanview. It was spacious and comfortable and the entire resort was looked after well. The beach is really good; had a quiet walk in the mornings. I had the time of my life at Big Kahoonay comedy show; boy it was wonderful.
You can check out Rum Point, which is pretty famous here. You can also try snorkeling at Morritts beach; it's really good. The best way to enjoy Cayman is to rent a scooter; it's pure thrill. ( but make sure you rent a good one; lol )
Actually, I did check out some of the other timeshares available there. Will tell more about that later.
