Check in/out timing...

We have arrived early a few times. Generally, our site has been empty so no problem at all. If it is not, we leave and return later. We ALWAYS leave before the stated check out time - we see it as being courteous. Once we arrived after check in to a large private CG near Disney World. We had made our reservation almost a year ahead, and I had called a week before we were scheduled to arrive to guarantee the reservation (we paid extra to pick a specific site) was still OK. I was told everything was fine. We arrived about an hour after check in and were escorted to our site that was not only clearly occupied by also clearly no one there planned on leaving. They weren't even there but everything was still totally set up. Chairs out, awning out, awning rug out, everything. We went back to the office and were asked to wait. After over an hour, we were told "apparently the other campers had chosen to extend their stay". Did they get permission to 'extend their stay'? "Apparently the evening staff approved it and they have paid for 3 extra days". Really? No, Really? My next question - "So which site will we use?" Our next answer - "We don't have anything available at this time". You have our money, paid in full for a week beginning TODAY, and NOW you tell us there is nothing available? My next question "So what are you going to do now?" The manager was summoned. He apologized. Once again I asked "What are you going to do now?" I was offered a full refund. I asked that he call around and find me a site at a competing Campground that was similar to the one I had reserved with him. He told me that was "against company policy but I will see what I can do". He disappeared. After 30 more minutes DH, even more annoyed than I, asked to speak with him again. Apparently he really did disappear! No where to be found. After another hour,(as I tried in vain to find another site somewhere else) as my blood was boiling, we were escorted to a site, and told it was absolutely the only one in the whole park. Our RV just fit - but we could feel every car that went by! The man who escorted u s there helped put us in so neither end would be hit by a car going by, but he also said it was really too small (he was great, BTW!). We had to park our toad about 1/2 mile away. We did get a full refund on our credit card from Tropical Palms, along with a written apology, but we most certainly will never go back! I know mistakes can be made, but the way we were treated was unacceptable. No one seemed really surprised or even very concerned. In more than 45 years of RVing, there have been more than a few times when reservations have been lost. One time, I made them for the wrong month! We showed up in March - I had reserved on line for May! The CG was also full, but the KOA in Tampa Florida found a spot for us - a site that was set aside and almost never used precisely for mistakes like mine. They were wonderful. DH and I have been camp hosts at several state parks. Each of them held a site 'in reserve' for 'unexpected circumstances'. We had to take advantage of this a couple of times. Once when the RV in a reserved site would not start and could not be moved to make room for the next camper. Once when a camper became very ill, had to be transported to the hospital and his wife needed to stay until he recovered (fortunately only a few days). Each time the incoming campers were very accepting and understanding. As the original post stated, Check in and Check out times are determined based on what needs to be done by the workers so each of us can enjoy our stays. Courtesy, following the rules, and treating others as you would expect to be treated makes it so much better for us all.
