When people choose to stay at Contemporary or Grand Floridian its not to show the World that we are Mr. Moneybags, we're doing it because we have an expectation FROM DISNEY, no one else, to give us their most Premium experience available. If there wasn't a market for this type of resort, they wouldn't exist. One thing to do to cater to that market is to offer certain perks that warrant the extra cost of that resort.
There are already a lot of those perks available to Deluxe guests that don't impede the moderate, value, or day guests in any way. For example, when we stay in Club Level we have our own private concierge that has a little more pull at certain restaurants, like Le Cellier or CRT and with a little schmoozing on his or her part, and flexibility on ours, 99% a table can be found for us at a relatively last minute. That doesn't mean that someone with a reservation at Le Cellier is going to be asked to leave the restaurant to make room for that person but its just an extra accomodation.
Giving the resort guests the opportunity to obtain fastpasses from the resort can be another one of those perks. No one is going to ask someone staying at All Star Movies to make way for the family from the Polynesian because their fastpass is "more vailid" than theirs. Will there be less fastpasses available at the machines? Probably. Will anyone notice that change? Probably not.
This has been an idea that's been put aside for too long.
