I've had the opportunity to attend the Pistol phase of the National Matches 3 times. First time was off base in a nearby motel (least favorite), the next time was in a cottage (the best), and the last time was in a module (second best).
The cottage comes with everything you need except food and firearm related stuff. 2 beds, AC, cable tv, kitchen with all utinsels, bathroom, and cleaning.
The module is like a motel room with twin beds, a bathroom, and AC. Our group started out reserving a couple of huts but kept calling to see if any modules or cottages opened up. Because peoples plans change you can upgrade without any penalty, but you have to call daily to see if there are any new openings.
I keep thinking I want to try the huts, just for the experience, but I'm not sure I want to rough it that much. I'm getting more appreciative of my comforts.
