Bring your own internet device, I have stayed in 4 different hotels in Thomasville and all of them blow. Different configurations on how you connect but in each case it is a horror to connect and stay connected. I run a couple of networks in St. Augustine at hotels and RV parks and I don't get calls or have problems. I keep it Simple / Stupid. This one was simple / stupid the stupid part was that once you connected you could not get anywhere. It is like Hooray you understand how to connect to a network. Congrats! Oh you want to get to the internet. I don't know how to help you with that.
Bring your own internet device as a for sure backup plan.
