We own at Morritts Tortuga and we love it. Let me tell you of some of the cheapest places to eat as that is where we frequent, though we cook almost all meals in. Now keep in mind that these places are for those who don't care about fancy and atmosphere but the food is good and oftentimes large enough to split a meal between me and my husband:
1) up the street from Morritt's is Vivine's Kitchen. Food is cooked at their house, you go up to the window, order, go take a seat at a picnic table behind the house on the ocean and they will deliver it. We shared a meal, though we weren't real hungry, and the cost was $11.
2) There are jerk places in Boddentown that are extremely cheap. You can either eat there or we usually get it and bring it back to the resort. We had always gotten jerk pork or chicken at Lorne's Jerk Shack in Boddentown but this past Thanksgiving when we were there we went instead to Chester's and it was delicious and cheap. Buy a large jerk dinner for $8 CSI (which is $10 U.S.) and get a small one for free. Lots of food for the two of us. We had leftovers. So the two of you can eat for $10.
3) If you can find out where Miss Cooney has moved her establishment since Hurricane Ivan, food was pretty good and inexpenive from there too. Again back before the Hurricane when we went there, it was her house too and she cooked out of her house. Don't know if that is the way it is now but I heard that she had re-established her business.
4) Food at Morritt's out on Mimi's dock is not badly priced for Grand Cayman. Neither is Over the Edge restaurant down the road a few miles towards Rum Point. Food was very good. Lunch cost me and my husband $29, including tip but no alcoholic drinks and no appetizer.
If you can take some food with you I would. Especially potato chip snacks (prick a hole in bag so they don't explode in your suitcase). I thought the prices at the groery store within walking distance of the resort, Fosters, did not have any higher prices than anywhere else on the island. If you wish to cook in a lot, Grand Cayman allows you to take in meat as long as it is unwrapped, in its original package with FDA stamp. We take it frozen in a cooler, even when we have flown commercial and it is still frozen when we get there. Many would think we are nuts to take the food that we do but it really saves a lot of money, especially if you are taking several kids with us which we sometimes do. We always take coffee, salt, pepper, sugar, crystal light, spices, those things don't take up much room.
Since you are going on an RCI exchange, it is highly unlikely that you will get oceanfront (The Grand is a separate resort next door but part of Morritts but if you traded for Morritt's specifically, you obviously didn't trade into The Grand, which does have elevators), probably poolside but they are only a few steps from the ocean and some of those units have a distant view of the ocean. But since you want a handicap unit you will need to get first floor as there are no elevators at Tortuga Club.
There is a kids club for the grandchildren. go to Morritt's website at
www.morritts.com. You can see their newsletter The Turtle Times which will show you activities going on at the resort and I think there may be some information on the Kids club. Have fun.
McCurley's is the name of the rental service tht picks you up at the airport and delivers you to the resort. Current cost is $250 u.s. for 7 days in the winter or $225 in the summer - add $50 if they brought you from the airport also. It used to be that they would stop at grocery store on the way to the resort for a few minutes to let you pick up groceries but I don't know if they do that anymore. They wouldn't stop on Sundays cause, as report, grocery stores are closed on Sunday. I've also used Andy's, Dollar, Thrifty without any problems.
