Just to be clear, you are suggesting that an alpine gravity roller coaster is a legitimate alternative to Disney World?
Really?
So I would fly cross country, stay in a hotel, get a rental car, drive to this place and for $15 each get an 8 minute ride. Sure for the cost of going to Disney World I could ride it 8 times. That takes up a little over an hour. Ohhhh Nelly! Don’t think I can stand the excitement!
Really?
No, just one of many suggestions that have nothing to do with the cultic world of silly, ignorant myths peddled by Disney to your kids (at high cost, per this thread). Families can do both. You can do whatever you like, wherever you like.
But you did pick the least thrilling item to tweak me over. While there, though, The Smoky Mountains also have an anuual Firefly festival you might enjoy...
