I do have to agree with you on this. Before FP was brought into the picture, if you were to do the big rides, or say even the entire mountain range and Indy, you'd have to do them when the park first opens. Everyone would be running to Space or Indy at rope drop. People still do that of course, but now with FP in the picture, you can either do one of 2 things if you do Space Mountain first thing at opening:
1. Grab a fastpass and then just go on Space Mountain.
2. Grab a fastpass and then go on something else, like Nemo or Peter Pan, or just go have breakfast somewhere.
Now with Fastpass, it gives guests - Annual Passholders and One Day Visitors alike - the convenient option to PLAN AHEAD!!! They can then go on it at any other time during the day and go on something else. In reference to the other thread, perhaps they could lighten up the restrictions a little bit. Limit the amount of fastpasses a person can get on a particular ride per day. Like say a person can only get 2 FP's on those rides per day, per visit. Say at rope drop, you get a FP for Space Mountain. Thats your first of 2 freebies. And you can't get another one for say an hour or two. But you're free to get another FP for another ride like Indy, Buzz, Autopia, Splash, Roger Rabbit, or Thunder. (Hard to believe those are the only rides that have it now. Use to be more.) But once you've received two on each of those rides, you're blocked for the rest of the day. But it still gives the guest the option to plan ahead. THAT is the convenience of fastpass. Disney just needs to provide a larger number for all guests.
