I don't necessarily agree with this because you're assigning a value judgment to another person's trip. The current state of the FP+ program might be a deal-breaker for some when they weigh the pros/cons (when they're going, where they're staying, how much they're paying for a trip, how far they have to travel, how often they go to WDW, how important the "big ticket" rides are, alternative vacation options, etc).
I agree with you. As someone who used FP extensively on all of our previous trips, the new system is a major downer for us. There are so many things I dislike about it, but they've already been mentioned countless times, so I won't repeat the mantra.
Our next trip is coming up in 2 months. If the inability to ride our favorite rides multiple times (without absurd wait times) is what we experience, I believe this will be our last trip to WDW until changes are made to the current FP+ limitations. However, if we can still manage multipe rides (with or w/o FPs) on our favorite rides, I will be satisfied. Ask me which scenario I think is the more likely, LOL.
Since our trips have been ride-centric, anything that makes it more difficult to enjoy the rides (multiple times) will be a negative for us. For others, whose trips are not as focused on the rides (particularly the headliner rides), the new system probably won't bother them very much.
But I refuse to continue to pay the ever-increasing costs of a WDW vacation, if the main reason I go to the parks (the rides) is negatively affected. From all that I have read and know about FP+, our ride experience will be affected. Just how significantly it is affected is the question, I guess.
I do know that I can continue to enjoy Universal's rides (which also has more challenging rides than Disney does), basically without limit if I stay in one of their hotels, and with very short wait times too. And the cost to stay at Portofino (a top UA hotel) during Spring Break is less than the cost of a Disney deluxe resort for the same week. It doesn't take a rocket scientist to figure out what place makes the most sense for me and my family.
This is obviously not the answer for everyone. But for those of us who enjoy the top thrill rides and headliners, it may be the wave of the future.
