ADR booking at 60-days plus your entire trip stay for on-site guests,
Important for IA$ - on-site you get to book IA$ at 7am, while off-site you have to wait until you get to the park.
That and the extra 30 minutes or extra 2-hours for Deluxe guests after hours are really the only benefits I think?
I think a lot of people will be making trade-off choices on
Genie+ and IA$ to fit things into their budget. I know I am planning to modify how I eat in Disney, I'll be renting a car since there is no DME anymore - so maybe start going offsite for food, nothing wrong with eating Chik-Fil-A for dinner
