Some hotels are a little behind in updating their systems for booking. The Ramada also has a few retaurants within walking distance. I would recommend hotel over camping. After spending all day in class/diving, you're going to be ready for a bed and air conditioning! As for the American Inn (I think that's the name), I have heard they cleaned things up since the bugman stayed there but I don't know anyone that's stayed there to confirm it.
I can assure you I won't be camping.
So, to sum up...
Quality Inn: Safe choice, $65+/night
Ramada Inn: Also safe, a bit cheaper?
American Inn: Maybe ok, cheap with Cave Adventurers discount (if it still exists)
Executive Inn: Beats sleeping in the car, cheap.
Hole in the Wall House: Very nice, but way too expensive alone.
Edd's trailer: Ok, and possibly cheap.
Plus lots of other alternatives...
If someone would go to the trouble of checking out American Inn next time they're in the area, that someone can expect a bribe in the form of beer and bbq when I get there.
