In theory, I don't like FP+. In practice, it worked fine for us on our most recent trip.
What I Don't Like:
1. We are Floridians, living about 3 hours away, so WDW is a weekend trip for us. DH and I loved the spontaneity of driving under the welcome sign and asking each other, "Okay, what park should we head to?" Our days are very regimented at work, so we want our free time to be less planned out. This was the first trip where I made our FP+'s at the 30-day window, which required buying the tickets in advance, planning which park for each day, and and visiting
MDE each day for three days to make the FP+ reservations for our three park days, exactly 30-days out. IT WAS A LOT MORE WORK THAN I WANTED TO DO FOR A WEEKEND GETAWAY.
2. We really wanted to ride 7DMT, as we had never been on it before, and DSalmost3 was tall enough (by one inch) to ride it as his first roller coaster. When I didn't get the FP's for that ride on my first try, I had to keep trying for three weeks, first getting us FPs at different times, then finally being able to book overlapping times. It required quite an effort that turned out to be worth it as we all enjoyed the ride. BUT IT WAS A LOT MORE WORK THAN I WANT TO DO FOR A WEEKEND GETAWAY.
3. Epcot has too many tier 1 attractions. I can see having to decide between Soarin and TT, I guess. But to include Illuminations and Living with the Land (seriously?) as tier 1 leaves too few tier 2 attractions to choose from. I booked Character Spot just because I had to book three, but we never went because no one was really interested in it. I'm not sure if this is a failing of FP+ in how they tier certain attractions or if it's a failing of Epcot in general not having enough "top" rides, but it seriously needs to be addressed.
4. Having a toddler makes scheduling a trip to the grocery store a challenge on some days. I did struggle with how to best schedule FP+'s for attractions he would like, never sure when the vacation schedule (late night fireworks shows, different meal times, an unusual place to sleep) would
lead to an unexpected nap or snack time. We were able to make it work, but again, I worried about it more than I would like for a weekend getaway.
What I Do Like:
1. We were able to ride 7DMT. Waiting in a 120 minute+ line with DSalmost3 would have been an incredibly unpleasant experience. With a hard-won FP+, we knew going into our MK day that we would be able to experience his first roller coaster ride together as a family. He smiled and cheered the whole way through.
2. We already live on our phones, so the MDE app was convenient. When DS took a 3.5 hour nap in the middle of the Magic Kingdom, we could reschedule the Buzz Lightyear FP easily. Within our 30 day window, when a dinner discussion turned to a potentially fun experience at WDW, I could just go on my phone and see if there was a FP available for it. I appreciated that flexibility and convenience within the system.
3. When we could, we made the scheduling work for us. I was able to schedule our FP's for Star Tours on a SWW right after the celebrity motorcade. Knowing that during the motorcade, ST lines would be short, we arrived early, and DH was able to ride his favorite ride on his birthday three times back-to-back-to-back-- twice in the short lines and once with his FP. I am sure there are other tricks like this we could use to our advantage with FP+.
I'm sure I could find more plusses and minuses, but those are the ones that stuck out for us on our most recent trip. We are both teachers, so we usually travel during peak times-- this trip was on Memorial Day weekend-- so these thought would probably apply for us to any peak time. Maybe some of my thought would change in we traveled in September or February, but that's probably not going to happen for us.
