Lillaskog Lodge is near central Groveland, CA and the Big Oak Flat entrance to Yosemite.

Yosemite Pines is the best option for groups of 2-8. They have cabins, yurts, conestoga wagons, and glamping options with reasonable prices. Some pretty neat and cozy spots there.

Thousand Trails is another company that has many similar options but they sometimes have two night minimums.

Airbnbs are still a good value for groups of 6+. As it turns out, October is a busy month for the area so single hotel rooms get pricey, but there are plenty of hotels and resorts nearby.
