Totally agree. I really had to trim ADR's on our park days, it was a royal pain to work around them, and impossible to change times. When you make ADR's months in advance it's like working with a blindfold on. Until the 60/30 day window opens you have no clue if FP+ times will conflict with ADR's.
We are going with extended family; and because there are very young children in our group I had to give top priority to FP+.
As much as I dislike the fp+ system if given a choice between fp+ being revamped and the adr system I say change the adr's. We never ever ever end up with the dinners we want or when we want them. Our last trip and this one coming the 2 things we most wanted were BOG, and the Wishes dessert party. Last trip I didn't plan early enough for BOG, and was sick Dessert pty day so had to cancel. This trip I booked bog for 2 different days, neither of which ended up working for us once our actual trip plans were finalized so I had to let them go. In my mind it is just nuts to have to book dinners prior to a time when most people book flights and hotels.
