You can even host a few other travelers up front in the separate living room on the two hide-a-bed sofas. This area will be perfect for cozy sleeping because of the fireplace, and you can even watch a movie as you drift off to sleep because of the 50" LED TV too. The full bathroom has a 48" x 30" shower with seat, and the kitchen has a breakfast bar that you can sit at to eat your cereal each morning
