Tried messaging multiple times prior to check in to confirm check in process and possibility of checking in early, no response. Finally called upon arrival, was told they had to confirm my reservation and would call back, after waiting an hour, called 3x no answer, eventually spoke to someone else who said property was double booked and offered a different stay in a different location and smaller, not willing to do reasonable refund. They cancelled my reservation and were extremely unprofessional in handling the canceled reservation. Expedia had trouble reaching them 1 minute after closing and cancelling my reservation. Not worth the hassle of staying at another property they managed.
