OP here...
We just returned from a trip to southern California where we made a number of stops. A real treat for us was booking a couple of nights at the Pechanga resort in Temecula {one of the finest in the country and featured on the cover of RV Magazine this month}. I made the reservation well in advance and was told that while mandatory check out was at 12 with check in at 2 they would be glad to let us check in early at 12 for a $10 fee that I was more than happy to pay.
I was asked to merely call head and give them a heads up that we would be arriving at 12 which we did. This RV Park is very popular and consequently nearly full every night with getting folks in and out in a timely manner being an ongoing challenge. When we arrived {after having called for our confirmation} the staff was very embarrassed to tell us the folks in our site had not left yet.
They sent someone out to remind them that that were late leaving only to report back that they had not even packed up yet and that it would be "a while". Now it was 90+ degrees out and we were looking forward to getting set up {water, sewer and especially the AC all connected so that we could get on with our day - we were only staying two}.
As there was no other site available and I had already paid for ours starting at noon I suggested they send someone else out again which they did. This time we got a better result and these folks cleared out around 1230. Not the end of the world by any means but it illustrates many of the points I made in my original post. Unless you have made prior arrangements {the folks in question had not} your site is yours and yours alone until the time slot you contracted for is at an end, it is really just that simple... just sayin.
:R
For the record the Peehanga Resort is awesome and we look forward to returning the next time we are in the Temecula area.
