Nashville is a great city. I don't think of it as a typical vacation destination like the beach or mountains, but we do in fact love to go there for long weekends every few years. We like 4-5 nights. For our very first trip to Nashville, knowing nothing about accommodation options, we stayed a night at a downtown "luxury hotel" on someone's recommendation. Another family we knew was also in Nashville. We met them at the Gaylord for dinner together (wasn't yet a Marriott hotel), and it was so overwhelmingly gorgeous and fun that we immediately cancelled our downtown hotel stay and moved over to the Gaylord. That was about 15 years ago, and since that time we've been back
to the Gaylord 5-6 times. We would never stay anywhere else.
Most of our trips were during Thanksgiving, and the hotel is always beautifully decorated for Christmas, and having the outlet mall next door makes it really special. Our kids loved it. Their Thanksgiving feast in the Grand Ballroom is amazing. The hotel is like a city covered by glass (the atria are gorgeous). We absolutely get lost in there every time! There's also a very nice movie theater at the mall, and we always enjoyed seeing several movies during those stays----the big holiday movie releases always made it great.
If you go to Nashville, I highly recommend the Gaylord, whatever it costs in upgrade......you'll enjoy it, and the rooms are great, albeit small compared to timeshare stays (obviously). Our favorite section, or atrium, is the Delta atrium, high level room WITH BALCONY.
Doesn't get any better than that. It's pricey, but we never leave without having had a fantastic time.
