Visted on a work trip. Normal checkout is 11, as a member we were able to request a 1230 checkout. We worked until after 4am, so we needed the later checkout to get some rest before the long drive home. At a little after 9am the cleaning staff was BANGING on the door, and when we didn't answer because we were trying to sleep they tried to come in, however the latch was locked so the pushed the door against the lock multiple times while loudly yelling "housekeeping" into the DARK ROOM. We made sure the do not disturb tag was on the door, and double checked it was still there when they were trying to come in. We went ahead and got up, and headed out as my husband and I both have a hard time falling back asleep after something like that. The front desk didn't really seem to care when I brought this up to them. I am still not understanding why housekeeping was even trying to clean a room that was scheduled for check out that day, or why they choose to ignore the door tag and were so aggressively trying to come into our room. Will definitely avoid staying at this property in the future.
