Cool staff. Funky location at big truckstop so it’s a bit loud. However, rooms are clean everything basically OK.

We had a wonderful stay! The hotel offered so much for families and kids — the large swimming area, relaxing hot tub, and sauna were all fantastic. There were tons of fun activities for the kids, including foosball, shuffleboard, and even a video game room, which kept everyone entertained. The staff went above and beyond — they were friendly, helpful, and made us feel welcome from the moment we arrived. A special touch was the complimentary freshly baked cookies and yogurt for kids at the front desk, which our family really appreciated. Our room was very clean and comfortable, and the entire property felt well cared for. One suggestion would be to ensure that guests with mobility challenges can access first-floor rooms more easily, as our family member had some difficulty using the stairs and only second-floor rooms were available at the time of check-in. Overall, it was a great stay, and we’d definitely come back again!
