GTS is a nice resort, comfortable with adaquate amenities but, IMO, it's best assest is it's location. It's one of the closest resorts to The Great Smokey Mountain National Park, there's a trolley stop a few steps away and, if you enjoy walking, it's within walking distance of the major tourist shopping street.
IMO the units could be a little larger (wider) but, after a day or so they begin to feel comfortable. The kitchen counters aren't granit like in the fancier timeshares and the bathroom definately was very swanky but, it was functional. The grounds we well maintained and sitting on the balcony looking over the courtyard area was pleasant in the morning and evenings. The kitchen was adaquately supplied.
It's a nice timeshare but, it's not a Hilton, Marriott, DVC or Westin quality resort. It really just depends on what you're looking for. High class accomadations with MF's that match or a comfortable place to stay with a great location. Owning a week at GTS wouldn't bother me in the least. It should trade very well and, it's a nice place to stay when you want to go to the Gatlinburg/Pigeon Forge area.
