Smoke alarm went off at about 4:00 am. Woke us up for sure. I believe my CPAP machine might have set it off. Turned machine off and alarm went off. Back to sleep. We had a death in the family so we arrived at 2:00 am 18th. We had made reservations for the night of the 18th but ended up paying for two nights. We were hoping for a refund for one night which we did not use.
