Suggestion: map a motel building somewhere in San Fierro. There are four motels in Los Santos, around ten in Las Venturas, but there are none in San Fierro. There are two hotels in San Fierro, one was mapped to be a casino, and the other one looks rather expensive. Having a cheap motel somewhere in the city would be a good alternative for players.
Role play around it: poor characters can temporarily stay in it, characters from other counties visiting the city can temporarily stay in it, it can be a hub for illegal role play like gun/drug deals or prostitutes taking clients there.
I think the best motel building design would be the one where there's a parking lot outside and each room has a door directly outside (like the ones in Fort Carson) as opposed to the door entrances being inside an interior (like Jefferson Motel in LS). I'll leave it up to the mappers to come up with something if people are in favor of this suggestion and it's possible to do.
^ That's not a motel, it's an apartment complex interior. The interior is good, but too grim for a motel (burning barrel and all), and from what I read it's intended for a rundown ghetto apartment complex.
What I'm suggesting is something along the lines of this in a San Fierro location:
