We recently spent a night at Mohegan Sun since we had tickets to a show in the arena. Overall the hotel is impressive when you walk into the lobby. We had paid over 600 for a single night - with tax and everything else, it came to more than $700. This is NOT a 700 hotel! Rooms are nice, but nothing spectacular. Linens and bedding a bit worn. Bed was pretty messy and sheets definitely need to be replaced (although clean, so that's a relief). Shower curtain had multiple stains on it. No turn down service. Gym had older equipment and multiple pieces of equipment out of service. For $300 or less a night, great. For 600-700, they need to up the ante, enhance the experience and provide a more luxurious experience.
