In another thread, I stated that my family and I were recently vacationing in Waikiki. On the evening of Sunday, July 20 approximately 9:00 pm my wife and I heard a knock at the door (22nd floor of a fairly nice hotel). To set up, we had just returned to the room about 10 minutes earlier. My wife was sitting on the bed and I was using my cell phone to check our bank balance. I assumed the knock was another family member (staying in a separate hotel room), but when I looked through the peep hole, I did not recognize the individual. I asked who it was and was told "security." I said "hold on" as I put on a pair of shorts (I had been in my underwear). Again, a knock on the door and "security." I looked through the peep hole again and asked for identification. "Can't you see my nametag," was the response (it was a simple nametag with no photo id). The guy had a walkie-talkie and I heard him say something into it about needing back-up as "they won't open the door." I assumed this guy was legit, but still didn't want to take any chances, so I opened the door just enough to let the safety catch on the door engage (kind of like a chain, but a solid bar). Not good enough, insisted I open the door. He's still talking about needing back-up, so I went ahead and opened the door. Said there was a noise complaint and wanted to make sure there wasn't a party in our room. I told him that we had just gotten back to the room and hadn't been making any noise. Said he would "let it slide" this time. I'm like "let what slide, we haven't done anything." The guy was a real jerk about the whole thing. I think he was upset I wouldn't open the door to start with. So, was I too cautious, or not cautious enough? Should I have called the front desk to verify before opening the door?
