It's true that the guide having it's own room is one of the requirements for the other NPC's as well. I haven't seen it happen myself, but if the guide gets stuck then he won't claim a room and no others will come. you can solve him letting zombies in by building a 2nd floor on top of your house with rooms. with any luck he'll go there and stay there, not walking in and out of your house any more.

Another idea is building a 1 room house specially for the guide where he can live on his own. this might help you if the guide is stuck too.
