While it may work at DL, it probably would be a disaster at WDW. 3 Hotels worth of guests can be absorbed intoi the FP system at Disneyland. WDW has 16, 19 if you count the villas seperately that are attached to regular resorts
I just did the Keys to the Kingdom tour yesterday and asked our cm about the fastpasses. He said they did not see changes this year. It would be too hard to give out fastpasses to resorts (Deluxe, moderate and value) also unlimited and paying for them. Who knows what time will bring!!!
I agree that Disney probably has too many resorts for this, but when we stayed onsite at Universal and got the unlimited front of the line, we LOVED it. It was a fun and relaxing vacation. But Disney still has my heart.
