Great park. We have been going there for years. We have never had an issue with size of sites, but then again, we are only 34'. However, I always found that I could park the car either in front or in back of the RV. They also have done a decent job of providing some buffer shrubs/trees between you and your neighbor. There are some areas of the park that are better than others, and though they do not in any way guarantee a site, you can ask for an area. Check their web site and look at a map of the park.
Enjoy Lake George and travel safe.
