Did the site you got have a concrete patio with furniture and a pull thru? >>THAT is the $60.00 site.
KOA has 'several' levels of CG sites to choose from, especially the KOA's near an attraction. They are all priced differently depending where they are in the park and what they offer.
After being on the road full time for just one year I got tired of 'guess what surprises and type of CG" I would be pulling into for the night.
I stay exclusively at KOA's now. AND I always stop at the Nashville KOA and REQUEST the $60.00 pull thru site with the concrete patio and furniture, cause I can, and I enjoy the extra space to relax on my trip south. :C
LOL! THAT patio site costs $116/night at the West Glacier KOA! :) Comes with a grill too! As a destination, it was great and we would gladly do that again. But probably wouldn't want to pay that much for a pass-through overnight.
At the other end of the KOA spectrum for us was the pass-through overnight site for $40 that was RIGHT NEXT to the freeway (literally no more than 50 yards or so...) AND train tracks with trains going through about every 30 minutes...in that case, the $40 was too much $$. Did not get much sleep that night...
