And yet multitudes will tell you they need all those multiple res so they can have somewhere to eat in the right park, working around their FPs, b/c they might only get 7D MT and Pandora only one day of their trip and if it's X day, they have to have an AK/MK restaurant picked for every day of their trip, plus the ones in EPCOT and their hotel...
Read these boards and you'll see just from board members that many pursue this strategy.
And it's no harder to be up at 180+10 than 28 - same process, just closer to the trip with more knowns known. There wouldn't be any more issues that PPO breakfasts are no longer PPO, that reservations got kicked for private events, that Disney just shortened/lengthened park hours or added parties for the day and now I can't eat there, that I can only get a FP for Pandora on the day I have my CRT res and I'd never get either again, etc...
