We spent this last weekend at the Flagstaff KOA on HWY 89 leading out of town toward the Grand Canyon. This campground reminds me of others that were built 30+ years ago before RV's got so big. The campground is really cramped. When we checked in, I discovered that the reservation people had made a mistake and could not fit the fiver in our reserved spot next to our friends who we wanted to camp with all weekend. They stuck us in a spot 3 rows away that was so tight we couldn't even set up chairs outside, let alone our awning.
They claimed there were no other spaces available. The next morning I went to the office and had a firm but polite conversation with the manager and after telling them I was leaving they ended up moving us to the row behind our friend's TT. The site was a bit bigger..still no way to put out awning..but I ended up taking out a tree branch with our A/C. Luckily no damage to the A/C. During the remainder of our stay I talked with several other campers/RVers who were complaining about the tight spaces and roads. I personally talked to 2 other couples who could not fit their rigs into the assigned spaces and left for the office or another campground. Others were worried if they did get the rig into the space they would not be able to get out. You could also see where the pine trees all around the campground had missing bark for mishaps with RV's. I think for someone with a tent or tent trailer this KOA would be fine, but not for folks with the bigger rigs. I know I will not be returning.
