The reservation system was a failure for us. We arrived at dinner time, about 530pm and another camper was set up in our reserved and paid for spot. All of the other sites were labeled as occupied. When we spoke with the host, we got excuses about not her having updated reservation info, not knowing that reservations could be made on Monday (4 days before our stay), and not knowing if the other sites would have people in them--even though they were marked as reserved. After almost 2 hours waiting for an answer about whether we could occupy a double site if no one else would be staying right next to us, we finally got word the double site was ours. The host also told us the person in our site was going to move first thing the next day. He finally moved at 1pm AFTER we got back from our hike. So, we moved into our site, set up our camp and finally ate our lunch. What we had planned to be a one-stop set up for two nights became a stressful and time wasting ordeal. Why even have a reservation system if the host doesn't have the whole story, or even know if the sites are actually reserved? I've stayed with Gallatin Canyon Campgrounds-run sites, and this was definitely not on par with the way they ran things in the past, and should not be allowed to be run in the future.
