The Park Vista was super nice. The staff were fantastic, the restaurant was very good, the coffee bar was a great touch, live music being played in the lobby/bar almost every night. The rooms were nice, very roomy refrigerator for a hotel room. The coffee maker is a pod type so keep that in mind if you are thinking of bringing your own beans. No in room microwave, but there is one near the elevators. The rooms could use a few more plugs, with all the devices now, our family of four was running out of outlets for phones/tablets/computers/smart watches, etc.
The pool was top notch. Two slides into two separate pools. A small kiddy pool and a hot tub. The upper pool was heated well, the lower pool was cooler which was good for when you got too warm. There is a snack bar near the pool which was nice. It's an indoor pool as well so weather wouldn't be a concern.
The trolley picking up/dropping off throughout the day is a perk everyone should take advantage of. With parking at $20+ per day, this is a great way to avoid that and still get to see all the great stuff on the strip.
The views were great, the building is iconic for Gatlinburg, there were bears to be seen, so make sure not to have any food in your car or it could get messy.
