We've had to deal with the change from the GAC to the
DAS with an autistic son who has limited communication skills and doesn't understand abstract concepts at all. The change to FP+ made it much better for him to handle, so for us it's a huge plus. We can FP+ the important can't miss rides for him without the stress of getting a return time or causing a problem that could lead to a serious anxiety attack. And we can do a FP+ for things like Toy Story Mania in the afternoon or evening for gosh sakes!!!
Last year, we went Thanksgiving week and didn't make FP+ reservations until we were onsite. Got everything we wanted, other than 7DMT, so we didn't ride it. We'll get it next time. The year before, we had ticket/cards for FP and did about the same amount.
I think the issue with the change is that folks felt the old system gave them their definition of their "money's worth", so doing less while paying more feels bad. Not for us, we're going as scheduled, got all our ADRs (even BOG for lunch on Thanksgiving week), and will have a wonderful family time.
It's not how many rides we do, it's how much time we spend together having fun, enjoying the Disney atmosphere, and doing our fave things - warm sake at Japan, multiple rides on Spaceship Earth at night, mini golf at Winter/Summerland singing and dancing along with the Beach Boys and other silly Christma music. Things change, we all get older, it's the Circle of Life (just saw Lion King musical last night lol).
As far as cost goes, we stay where we can afford that year, and we feel it's a good deal. We're looking at 4 days in August in Washington DC to see the free Smithsonian museums. Our room will be approx. $250 a night, plus $28 for parking plus tax, so at least $300 a night. Food costs are around $200 a day, DC restaurants are expensive. So for 5 days, 4 nights in DC, we'll be spending almost $2,000. Not sure if there's enough value for us to do that. But a week in Disney for $3,000 - far worth it to us!
