If you have to sign on and do a little work, Frisco Woods is not a bad place to do it!
Their wifi at our site was unusable... and I loved it! Very nice campground.
They have installed Wi-Fi repeaters all over the campground, but internet access is spotty. I noticed that when a lot of people are in their camping units, probably streaming movies, their Wi-Fi bandwidth can't support all of the users. During the week it was better, but I relied on my Verizon Hot Spot for access.
