The main thing to remember about this resort is that it doubles as a timeshare, AND it's on the opposite side of the island from pretty much everything. The result is a place where you can truly unwind and enjoy being "off the grid" as much as you want to be.
The rooms are nice, and we booked a studio suite. The floors, as with most Caribbean locations, is completely tiled. There's a jetted tub outside the double sink and then a water closet with a standup shower. Seemingly endless hot water and great water pressure in both the shower and tub.
The bed is adequate, and it seems that all balconies are both large and have a great view of the beach/ocean. Some balconies, however, are semi-private and only separated by a hip-high wrought iron divide. No big deal, but if you're waking up, you can see you neighbor if they are at the railing, looking at the ocean.
We ate at the beach grille once and the food was very good. Also did the resort breakfast as part of the Euro-plan, and were pleased with the freshness and portion size. Other dining options included going to the grocery store across the street, and there's a little Italian place that cooks up great food for either dine-in or take-away (their hand made, wood stove cooked pizza is terrific! You're about 1.5 miles down the road from Tukka, which was fantastic as well.
As far as activities, we were only here for diving, and we booked with someone who departs from the Northwestern part of the island. We rented a car and had no trouble getting to and from the other side of the island within 45 minutes to an hour. It's a lovely drive, and we were happy to cruise at the speed limit.
Overall, The Reef is away from the fast paced side of the island, but offers a great place to unwind, and relax. We weren't able to stay completely off the grid (work never ceases), and the wifi was affordable (by resort standards) at $40 (US) per week.
Should we return to Grand Cayman, this would definitely be a place we'd stay again.
