And how long does it actually need to be occupied to meet your definition of "use" ??? An hour? Eight hours? Continuous or in the aggregate?
And, if for some unintended reason, I did not "use" my reservation the night before, could I convince Disney to refund my money because I did not "use" the reservation?
In fact, if you don't show up at all to check in for your reservation, doesn't Disney CHARGE YOU IN FULL for the first night, or do they gladly refund your money since you didn't "actually occupy" the room or campsite?
It is not gaming the system if a room or campsite is reserved and paid for. If, by doing so, my intent is to "use" the room to get free parking, advanced FP+ reservations, or any other perks provided in return for that room reservation and payment, then it meets my definition (and Disney's) of "use". There is nothing in the reservation agreement with Disney that specifies otherwise.
