Resort is pretty good. We always stay in the Grand or the Londoner, so right on the beach. The staff is pretty solid and there are several folks working there that we've known for years. Used to hang with some of the sales folks, even at their homes for dinners/parties, but all have moved on to other Morritt's resorts or out of the industry entirely. No, we did not ever hang with Armie Hammer (or encountered him for that matter) when he briefly sold timeshares there after he went nuts on that woman from Dallas.
Driving on the left is pretty easy. Easier if you rent a right-hand drive car, believe it or not (at least for me). Just take it easy at the roundabouts and try not to feel too pressured to blast through the busier ones. Also, watch out for the yardbirds and crabs - they're pretty much everywhere.
We always fly in on a Saturday and stop at one of the bigger Foster's to load up on groceries and a liquor store for any booze that we didn't buy at duty free on the way in. We make breakfast and lunch in the condo and then eat out or get takeout for dinner. Most places are closed on Sunday, including grocery stores, so unless you want to eat every meal at the resort on Sunday, get groceries on Saturday. The dock bar at the resort is also cool for evening meals if you don't want to eat in the dining room - the food all comes from the same kitchen.
You can also charter a boat for fishing and Captain Herman will cook your catch. When we've done that, we've always enjoyed it.
The pool with the swim up bar is meh, but to each their own. They do games and shit and it's loud (PA system and microphone) and so fuck all that. There always seems to be a kid squeezing out a Baby Ruth in the pool every trip, shutting it down for the day.
It will be fucking windy when you are there.
