Well, you could just already be in the hotel. Most of us already were, for reasons that are not told. Most of us are in the lobby though, so if you want to meet us that's where it'd be best.
Me, I suggest that you are already in the hotel, trying to fortify your room. You hear something going on, maybe it was us maybe it was walkers, but for whatever reason you leave. If you need my help on this too, just say that a whole group of walkers broke in and you had to beat a hasty retreat. You got nothing but the clothes on your back and your knives, so he figured that you might as well just go find somewhere else to set up shop. Then you run into us.
