OK, so based on posts so far, it looks like the list is:
Diamond
Westgate
Bluegreen
Shell
VRI
Vacations Internationale
Worldmark (operated by Wyndham, but not the same)
Do all these systems utilize a currency (points) to allow owners at one resort to easily utilize others? Or are they really loose networks of privately owned resorts similar to RCI or IL where you trade a week for whatever else other owners have traded in?
I currently own a membership with Melia (which has good Mexican, Dominican, and European locations) and Wyndham (good Florida locations). I have younger children and live in New England. We like timeshares for the money it can save buy cooking in the room. I’m interested in a network that will either have additional geographic coverage (such as New England beach areas, or the Caribbean beyond DR), or which will provide same coverage at either (a) same annual MF price but higher quality, or (b) same quality but lower annual MF price.
Any recommendations?
