The new changes will allow for a five minute window before the time listed on the FASTPASS ticket, and a fifteen minute window after the ending time listed on the FASTPASS ticket. Apparently, this is the first stage in a new system that Disney plans to implement in the near future. The new system will be called NextGen FASTPASS. The system will be much more strict than the one that is in place now.
Personally, I never liked the FASTPASS system in the first place. The theme parks are so big that by the time it reaches the hour on your FASTPASS, you are far away from the attraction the FASTPASS is for. As long as you are not at one of Disney’s theme parks during their peak season, you won’t have much of a problem waiting in line with everyone else anyway.
A poll was taken on one of the Disney related forums in which it appears that every one in four Disney theme park visitors disagree with the changes. Others are just nervous as to how the new system will work, but many say they already get to the rides within the time listed on the ticket, so the changes will not affect them in the slightest. I guess it is just a matter of opinion, and whether or not you mind being tied down to a schedule while on vacation.
