Here's a link to the guest room layout (couldn't find a photo).

The lockoff is basically a hotel room, with a queen bed and sofabed. There is a "kitchenette" that is outfitted for 4 (plates, glasses, etc.), with a sink, small fridge, microwave, and coffeemaker.
Just FYI, the rooms at the Marriott Resort hotel (recently refurbished) are larger than the lockoff rooms at the Surf Club.
I think I'm supposed to get an AC for every year left on the old II account. I wasn't expecting it and I was especially surprised to see Aruba on the grid.
