See, having adrs doesn't feel locked down or held back in any way for us. It sounds like we'll spend a lot of time trying to track down food at a place with food we want to eat. Ah, that epic day when dh needed to eat an hour before but family didn't want an adr then the line for via napoli was long and the cranky ones wouldn't wait and then sunshine seasons was closed and and and...not fun.
Having adrs gives structure to our day and makes sure we get to eat at places with food we like! And it makes sure the ones in the group who, whether they want to realize it not not, need to eat regularly so they feel better and don't drive the rest of us batty, get to eat regularly.
So to me it just sounds like the work you listed putting into it at 180 days will get down on the fly. While hungry. If you don't have family members like mine I'm very glad for you!
This is why I made a few. With my (younger) kids, it's easier on me to have a known break and some food while touring, even though they resist. My youngest was a constant snacker with all of the activity and we had to take a short breaks, every 30 minutes or so, to give/buy him something. That was a pain and I hope my accommodations for him, this trip, work better...or at least I deal with it better! My other two had very low appetites and didn't want to stop to eat even though they needed the fuel.
Seating for our past ADRs often ran late and that added stress to my day with Jedi Training, FP, shows, etc to get to. I've scheduled NOTHING for hours after a planned sit-down so that I can actually relax.
I'd go ADR-less with DH in a heartbeat!
