We stayed in the Tuscarora village loop.  The sites there were non-electric.  There was one central bathroom/shower house, so if being close to a restroom is important, choose your site accordingly.  Some of the campsites were quite a walk from the facilities.  Many of the sites back up to the woods, making them feel more spacious.  There are also sites that are very close to together and we saw several extended family groups using adjoining sites - one for cooking, one for sleeping and one for hanging out. here is a wonderful playground in the Tuscarora loop.  There’s another great playground next to the swimming pool.  The town of Watkins Glen is adjacent to the park and has lots of little restaurants and shops - even a Ben and Jerry’s scoop shop!  The town itself gets very crowded with people arriving on tour buses to see the waterfalls, and the bottom half of the Gorge Trail can be very busy.  The rim trails and the upper half of the Gorge Trail were much less crowded.
