It is insane, I have never had a hotel put $100 hold, then once I charge the first $100 put another hold for $200, then once I charged another $100, put a new hold for $300, which according to the reports above is what they are doing.
I have no problems putting a $100 hold, then once I have charged $100, putting another $100 hold on and then after going through that, another $100 hold, that makes sense and is what most hotels do, this would result in $300 worth of holds, what Disney is doing would result in $500 worth of holds, there is a very large difference here and over a long vacation will amount to a very large difference, so yes, I stand by the idea that their policy, as currently implemented, is insane. Follow standard industry practice and either do as above or as I previously mentioned with the "hold voids" and this won't be an issue, but as presently implemented they are not following industry standards.
But since we will be on the dining plan, then if they suspend charging to the room because they went over the limit due to how they are placing the holds, then it simply means we won't be spending money in the parks at that point.
