I wanted to write a review to help balance out some of the negative comments about the construction and to give a clearer picture of my personal experience. Yes, the hotel is currently undergoing construction, and yes, the rooms could use an update—but I still found the property to be really lovely. The pool area and gym were fantastic, and the construction never interrupted my sleep or overall comfort. While dining options were a bit more limited, I ate at the restaurant by the pool and had a great meal. I also took two fitness classes at the gym, both of which I thoroughly enjoyed. If you're looking for a picture-perfect resort experience, it might be best to wait until after construction is complete. But if you're open to enjoying a beautiful property at a discounted rate—with some construction nearby—I highly recommend staying here. Bonus: because of the ongoing renovations, nothing felt crowded. I had entire pools to myself, the water was warm, and the overall atmosphere was quiet, calm, and relaxing.

My wife and I just returned from what was supposed to be a 4-day vacation at the Biltmore, but it was so incredible we ended up extending our stay for a fifth day! From start to finish, this resort exceeded our expectations in almost every way. Our room was absolutely perfect spacious, clean, and beautifully appointed. It was a true sanctuary after our fun filled days. And speaking of fun, we took full advantage of the amenities. The adult pool was a peaceful oasis, and we loved the variety of food options available on-site. Every meal was a delight. The bars were a highlight! The bartenders were not only friendly but truly skilled, crafting delicious and creative drinks. The service throughout the entire property was consistently warm and attentive, making us feel so welcome. We're normally not the biggest gym rats on vacation, but the fitness center was so well-equipped we actually looked forward to our workouts. The pickleball courts were an absolute blast and added a fun, active element to our days. And the spa! What a gem. The services were spectacular, and we found the pricing to be very reasonable for the quality of the treatments. Now, for complete transparency, the in-room TVs were down for the first two days of our stay. While we would have enjoyed winding down with a movie, honestly? It barely put a dent in our experience.
