Finding license info for many resorts and attractions is often futile, if they even have a license. These attractions are often owned by some obscure corporation.
In the case of Lake George Escape, they are owned by Equity Lifestyle Properties that owns hundreds of Mobile Home Parks, Campgrounds and RV Parks around the country. For RV and Campgrounds they have 2 subsidiaries: Thousand Trails and Encore Resorts.
Encore Resorts owns Lake George Escape and also Lake George Schroon Valley and Alpine Lake in your area. The only license found in a nationwide FCC data search is a VHF license for Equity Lifestyle DBA Thousand Trails for VHF at one site in California.
If you see a site with radios, Close Call is probably the only way to find their frequency. Illegal use of GMRS or Color Dot radios is very common with use of legitimate FRS or MURS radios also a possibility. Licensed use of Color Dot or other business frequencies on a wide area basis issued to the parent company is also possible.
