If you check out Connections123.com, they offer a 4-day Park Hopper Plus pass - the only place I've ever seen it. It's ~$200, if IIRC, for an adult and includes one Plus feature. This is the same price other sites offer for just the 4-day Park Hopper with no Plus features. Order thru them and it's like getting free admission to BB.
It's too late to do this now probably, but I would also recommend getting a premium credit card for future trips. I have a Kroger visa card where you accumulate reward points for every dollar you spend. One of the rewards is $50 gift certificates for Marriott properties. I charge just about everything I can, including my property taxes, in order to accumulate points. (Note: this only makes economic sense if you pay your card off every month.) There's no annual fee for this card.
Using my rewards, I've earned $250 in Marriott gift certificates that can be used for overnight stays when we drive a long distance. Nothing like a free night!
