The National Park is FREE!
Go to Wonderworks in the morning.. then go do other stuff, back to wonderworks (passes are good all day) later.
You can take the trolley, but if you have a car, it is much, much faster. Long lines of traffic follow the trolleys!
For a local place to eat - big portions, good food, cheap - Try Gondolier Italian. Turn left at Main Street/Dolly Parton Parkway/411 - about 4 miles down on the left. The A&W (fast food) on the same street, but on the right, is also locally owned and operated. They have the best, fresh root beer you will ever try! The owner, David O'Shields, is generally working inside. He really supports the community. If you like Thai food, Thai Basil is very close to the Wilderness - in the shopping center with Staples. We just ate there

Super yummy and a locally owned and operated restaurant.
Yeah, Wal Mart is crazy...not so bad in the mornings. Kroger is very close to you and a nice grocery store.
Also if you have a hankering for a pedi, Diva nails is in the shopping center with Staples. Best place in town! Ask for Jollie!
