We are staying at Poly GVC (5+2 deal) and have added the silver plan. I figure we will eat most breakfasts in the concierge lounge (one or two character breakfasts), then use our wishes for sit-down meals, HDDR, watermouse rentals, my husband is golfing one day. I know we could probably do without the silver plan, but I figure everything will be paid for in advance (with the exception of snacks and F&W festival) and we will not think twice about where we decide to eat.
Good luck!
