I am not sure if you mean hobby friendly hotels but I'll give you my best answer to that question, although I don't think it's wise to name specific hotels.

For out call I don't think that it really matters too much and any three star or above hotel will meet your requirements.  However, some hotels require a room card to activate the elevator.  That means that you either have to meet the lady in the lobby or hotel bar or off site.  One problem is that some of these hotels have smaller lobbies so it is a bit hard to be anonymous, but so long as you don't come down in a bathrobe, you should be okay. Some of the business friendly hotels have larger lobbies that are often filled with happy customers, so it is easy to blend in.

I did hear a bit of disturbing news about one of the elite hotels in town, but I am unsure how that would impact a casual monger who orders out call.
