I'm sure there are many guests that choose not to participate in the existing FP but I know from experience that there are also many guests that don't participate because they don't know how it works or don't know that there isn't an additional cost to use it.
There were more than one occasions on our last trip where we zipped through the FP line and overheard kids in the standby line ask their parents why we were able to move through so much faster and their parents said it was because they didn't purchase those types of tickets.
We are in complete agreement here. With that said, my main points are:
1) Do we really believe that FP+ usage is going to be dramatically higher? Again, you've got the current simple-as-can-be swipe card system vs bracelets/smartphones/
MDE.com/advance registrations (which I agree optional.)
Most of us here are viewing FastPass as veterans of the parks. Many plan meals 6 months in advance and have detailed spreadsheets of their day attraction-by-attraction.
Meanwhile there are thousands of guests who arrive for the day with no advance planning, no knowledge of FastPass, no gameplan for riding attractions. While advance planning is not necessary with FP+ the entire system is far more complicated than legacy FP for the uneducated guest.
Personally I will have no problem with FP or FP+. But when I consider people like my parents, father-in-law, neighbors or coworkers being dropped in the middle of WDW for a day trip, they will have no understanding of the system and no patience for rubber bracelets and touch screens.
2) And with that said, the main point I'm trying to drive home is that any projections of FP+ capacity are fundamentally flawed with no access to hard data on guest usage.
The third sentence of bcrook's post reads: "Total FP+ needed per park per day based on the idea of 1 e-ticket FP+ and 2 other rides."
Then it uses annual attendance figures to project average daily usage, assuming that every guest gets those three FPs each day.
What it fails to take into account are:
1) Guests who will ride zero or very few attractions.
2) Guests who will take (reserve) a FastPass and then not use it. That number gives Disney the ability to inflate FP issuance since some will always go unredeemed.
3) Guests who simply will not use FP or FP+ no matter what.
4) In the case of FP+, guests who are hopping from another park and thus do not get any ride reservations in the second park.
Every one of those factors chips away at the number of reservations required to satisfy the actual group of FP+ users...which will be far smaller than the daily admission average.
Meanwhile the grouping of attractions further limits which attractions I can experience in a given day. And the addition of new FP experiences to each park adds more capacity to the whole system.
I really don't see how FP is going from a system where I can reasonably--without any abuse or subterfuge--get 4-6 tickets per day for "E" and "D" ticket attractions, to one where its maxed out with me only getting one "E" ticket reservation and two lesser attractions.
Because FP+ is being communicated out to guests prior to their stays (I'm assuming they'll continue to do this after testing is complete) we may see more guesting using FP+ than traditional FP. It's hard to say though.
That's all well and good for Disney hotel guests...the most educated group. But again, thousands of guests daily who just drive up and pay their $95 for one day at the Magic Kingdom or Epcot. They won't understand FP+ and many of them won't have the tolerance to stand in more lines or even be accosted by a helpful Cast Member who they perceive is just trying to sell them something else.
I think it's kind of like ADR's. I think many folks that don't book their ADR's ahead of time don't do it because they don't want to; I think they just don't know they need to. FP+ may end up being the same way depending on how well Disney communicates the process to them.
ADRs are a poor comparison because the capacity is so low. We're talking a few hundred parties per night dining at CRT or Le Cellier vs. attractions which can handle 10-30K per day. It doesn't take much to max-out ADRs at several locations.
