Fast forward 45 minutes. I had been on the phone with my sis and made no mention of the man because at that point I'd calmed down and decided I was being silly. Right before we hung up though my sis said, "Just be careful, okay?" Now we are not a family who says "be careful" and "I love you" on the phone so I asked why she said it. She replied she just had a weird feeling, so I told her about the man. We decided I should call the front desk and at least see if he was staying there, so I hung up with her, put a chair in front of the door (because of course I was scared again) and made the call.
I told the girl at the desk that I knew it was crazy, but there was a guy on the property who was kind of giving me the creeps. She immediately replied, "With the red shirt?" I swear my blood ran cold. Turns out he was a guest but he'd been walking around for the past 3 hours and intermittently coming to the lobby only to abruptly leave when another guest entered. The check-in girl was so freaked she called her roommate to stay with her until her shift ended. After I hung up I could not stay there through the night so I packed up, ran to my car and drove around to the front to check-out and get the story from the girl. She was just as scared as me. The guy had an out of state plate and even when he didn't enter the lobby he would stand outside and peer in. The girl had the distinct impression he was trying to get her alone. Needless to say I haven't stayed at that hotel since. Sort of anti-climatic there but words cannot describe the terror (not an exaggeration) that I got from the presence of this man. I fully expected to hear about a murder the next day at that hotel. Thankfully that didn't happen, but even now if he were to flash across the television as a serial murderer I would believe it.
