We love going to Lake George RV Park.  It's got large sites, virtually all blacktop roads, bike trails, dog park, indoor pool, outdoor pool and another (new) water park with zero-entry pool.  Great store on-site, Movie theater & shows/entertainment, tennis courts, ball park, paddleball courts.  Pretty close to Lake George Village and the lake, but not on it (about 5 miles).

My only minor issue was with WIFI on one trip, but most of the time it's pretty good for a campground.

We try to get there once or twice a year.
