Where was it located? That would be an option for me if I am able to attend this meet. The exterior corridors are a plus in my book.
Why do you like the exterior corridors?
The convenience of having the car right outside the door, it's easier to take belongings in and out.
If you're lucky enough to get a room on the ground floor, or the chain will let you reserve a ground-floor room (as I've done with some Comfort Inns in Canada, at extra cost -- interior corridors, but the ground-floor rooms have back doors).
Some motel listings specify rooms on the ground floor in their descriptions. I always request the ground floor and that request is most usually honored. My knees don't like stairs, but I don't really need a handicapped-accessible room (plus I hate the roll-in showers that most of those rooms feature) and I hate to take a room away from someone who might really have need of it.
The situation you describe -- doors to both the inside and outside -- is a feature on the first floor of the Best Western in Frankfort, where I sometimes stay for work. I've also noticed it at what was, at the time, the Ramada I stayed in at Rutland several years ago when I attended the Bennington meet. That one was interesting in that you couldn't open the door from the outside, only the inside. So the solution was to go inside empty-handed, then open the door and bring the stuff in while keeping the door propped open.
