Ill freely admit to booking a throwaway room, and it was strictly for financial reasons. One night at a FW campsite was $55. For that amount, Disney chooses to provide a list of services including free parking on check-in/check-out day, Magic Bands, EMH, FP+, ability to reserve BOG FP for lunch, and of course access to a campsite plot. If I pay for it, how I choose to use any or all of those services is up to me. And we all have the same opportunity to reserve the campsite. I wont apologize for planning ahead.
My extended family of 9 stays offsite in a 4 bedroom vacation home for a week, which is significantly cheaper than all of us staying on site. Without the throwaway room, we would have paid $34/day for two cars on check-in/check-out day ($68 total) and we would have bought 4 Magic Bands for the kids ($52 total). So for $55/night Im saving $65. Thats not even counting the FP+, BOG FP and EMH benefits (which we arent using since some of the family havent bought park tickets yet) and the Magic Bands for the adults (which we wouldnt have bought otherwise). So while booking a throwaway room may seem like a lot of work to some of you, Ive done a lot more to save a lot less in the past.
Even if Disney closes the FP+ loophole, it would still be worth it for me. Im sure as soon as Disney starts losing a significant amount of money on throwaway rooms, theyll address it. But for every time someone cant book a full week because a throwaway room, theres another time that Disney makes money on a throwaway room that would otherwise be unoccupied.
