They did that to me years ago in Wells Beach, Maine. It was a weekend and I usually spent at least a week there and it was about a 4 hour drive from VT. But, we tried, on a whim to go their for just one night. Arrive on Saturday, late morning and leave on Sunday. I was surprised that they were doing that because it was off season but it was two nights and frankly because I didn't make a reservation it was a particularly nice weekend, it was busier then usual. I'm sure there were some available for one night, but I didn't have the energy to keep looking. The kids wanted to go to the beach. So I reluctantly took it even though we had to get back to Vermont by Sunday evening because of work and school attendance needs. I wasn't really upset but it did make me a little miffed, nothing serious. Having been going to Wells Beach for many years that Saturday was a really lucky treat. The warm Gulf Stream was running very close to the shore so you could go in the water without fear of hypothermia. My kids usually stayed in the normally cold water until their lips would start to turn blue and we would make them come out. So we spent the afternoon at Old Orchard Beach and went to Lord's Harborside Restaurant (closed now) fill up with wonderful seafood, Sunday breakfast at Congdon's Doughnuts morning to the beach, (the water was back to its normal polar bear temp. and left after lunch at the Goldenrod Restaurant in York Beach on Sunday.
Anyway while we were sitting on the beach I came up with a diabolical plan to give the room key to a homeless person to stay there after we left to go home. Sadly, my generosity was thwarted by my wife telling me I couldn't do that. Instead we never checked out. We just left the keys in the room and left for Vermont. I just didn't want them to rent the room again after I had already paid for it.
I know this has nothing to do with WDW, because even paying for two nights in that hotel and adding up the cost of lodging, meals transportation and entertainment, plus real, honest to goodness, relaxation with no massive every minute planning, that is just one example of things that can be done and not spend even a quarter of what one day at WDW costs. WDW was great and was my escape from everyday life, but even though it was always undoable for a large part of the country, the middle socioeconomic section was always able to find a way to get there. Now the choice is send your kids to college or go to WDW. You can't do both.
