I have only ever stayed in the cabins and they're nice! Elberton had garbage cell reception but the cabins all have WiFi. When I'm busy during the day exploring I don't care about cell service but I sure like checking out my phone before bedtime!
They added high speed internet to campground. So wifi calls work great. The park is beautiful and the staff is very friendly. We were the camphosts on site 19 for August and September in 2023 and would gladly come back in the future.
