canu get a person with out an account to stop visiting ur hotel over and over again! please help!!!!!

No, you can't.

I looked at your hotel... there are a few dry guests in there... do you mean them?

No, and isn't that good for people to visit?

I saw your comment in your guestbook. Dry guests are artificially created (by the game engine) guests that come to your hotel. It's a feature that brings you more guests (for free, if you don't invest in marketing at all). Build more rooms if you need more space for wet guests (real people).
