We have our first trip camping at the Fort scheduled for July, so I can't comment on staying at the Fort from a personal standpoint.
However, we bought a travel trailer earlier this year, and we have enjoyed it so much. We can afford to take more vacations than we did before since campsites are less expensive and we can make our own meals. (Gas is double, however.)
I have never liked hotel rooms at all. I have enjoyed being able to enjoy our outings (water activities, theme parks, etc), then returning to our campsite to our own beds, our own sheets and blankets, and it's all CLEAN. It's a bit like going on vacation, yet going home at night (even though the beds are different than the ones in the house, they are still ours).
We also enjoy being able to have familiar food that we would eat at home. If we go out to eat, we can put leftovers in the refrigerator and enjoy them later.
Although we haven't brought our cat with us, many people vacation with their pets.
Although our camper is smaller than the average hotel room (I think I figured that we have 200 sq. feet), it is laid out in a way that we have our own space. We have our queen size bed at one part of the camper, and the kids have full-size bunk beds in their area. It's all one big room, but there is space for all of us. We also have a booth dinette that seats the four of us (we usually eat outside unless the weather is bad, however). We have a sofa and a tv. The kitchen is small, but it works for us.
I know I've said it before, but it's comfortable and clean.
