We did this right after we first bought in. We went to each of the properties, walked around on our own for awhile and then asked to see a unit. Almost all were able to accomodate. At Vero Beach, they even let us wander around the Beach Cottage for a bit. Boy, did we have visions of great family reunions in that location!
Enjoy checking out all the places. We've stayed in 5 so far and I'm looking forward to checking out the rest over the next few years.
