I have a confirmed Marriott exchange through II in July 2012 and need to cancel and re-trade for the week before. Have been calling for weeks trying for a re-trade, but no availability. My other option is to cancel and take a replacement week to put in a request. According to most II reps, the replacement week is then considered a non-Marriott and when making a request, I now need to give 3 resorts or 3 dates?!! What Marriotts are nearly impossible to trade into during early July??? I would request 2 of those and the one I really want. Any suggestions??
