Can anyone tell me if RCI members can trade into Marriott's Grande Vista? It's not listed on RCI's web site and I don't have a new book. My parents can trade with II and we can trade with RCI and we were hoping to both be able to stay at MGV. If we can't get into MGV does anyone have a suggestion as to where to stay that is just as nice that we can both trade into? Thanks for your help!
