OP, I hope you and the family have a great trip to Jamaica! Cayman is very pricey, especially on the 7MB, but resort hotels like the Westin can be very expensive and they charge daily resort fees.
The Wyndham Reef is very nice but it may not be as desirable for the non-divers because it is about a 45 min to an hour drive to 7MB and many of the island's most popular attractions; but if they are just looking for a place to relax in the sun then it is fine, and there are a few nice restaurants and things to do on the East End.
If your group decides to head back to Cayman some day, or just you and your wife, it would be best to book a condo or an apartment. You can find 1,2, and 3 bedroom condos and some are on 7MB (and others are not) but many have daily maid service except Sunday. We go to a lovely spot that is 10 to 12 miles from George Town and 7MB and we are on the beach but it's not the 7MB, but there is snorkeling right outside and it works well for us and much cheaper than a venue like the Westin.
We don't look for an AI on GC because there is no need, there are lots of restaurants, grocery stores, and it is safe and easy to travel around the island. When we go to the sister islands of Cayman Brac and Little Cayman we prefer to stay at a small, diver-dedicated all-inclusive because it is easy and there aren't many choices for restaurants or groceries, but it is still safe to travel around all the Cayman islands.
Whichever Cayman island you pick, eating out 3 times a day is very expensive, so it is good to have the option to prepare some of your own simple meals and eat out part of the time, or go for one of the few all-inclusive dive resorts.
