Checked in at 5 PM, left belongings in our assigned room, had dinner and attended an event. Returned to assigned room, to find another family in our room. Spoke with room attendant at front desk and was told no sir your family belongs to another room. 2nd family thought it was odd others belonging were in the room, luckily nothing was stolen and we were able to get out belongings and our “new” room wasn’t occupied.
