I have been in this situation many times and have handled it different each time depending on where I was in life and in modeling.
There was a time I needed the money to get out of a bad situation and I would shoot for anyone that was paying me. Do I regret a lot of that work now? Yes I do...I cringe everytime I come across one of those old images on a site somewhere. I never thought I would feel that way as long as I was being paid. Keep in mind if you are hoping to do more commerical style stuff, it might hurt your image in the eyes of those doing the hiring if they happen to run across them.
On the otherhand, I worked with a photographer who was a beginner (mostly shooting in hotels) and was really anxious to learn. I helped him with the styling and backdrops as well as the actual images. We converted some of the ones where the lighting was off to b&w and they ended up being beautiful. A lot of so-so or bad images can be salvaged w/ some work in Photoshop. For instance we cropped a lot to make bodyscape and artistic styles rather than glamour.
I often get the feeling that photogs who just have an entire portfolio of bad hotel shots are often the ones who just want to see chicks naked! They should have some landscapes, children, headshots or SOEMTHING else. If they cared that much about bettering themselves or showing the models in a good light, they could learn PS and edit the images to salvage a few and make them look less like they were shot in a hotel. If you have to shoot in a hotel, thats fine, but there is no excuse for not bringing backdrop fabric or paper and/or trying something different.
If I do feel someones work will show me in a bad light, I ask what the images will be used for. I always find out if they will be used on their personal portfolio, an amateur adult site, or never even online (a lot of people I have worked with don't even post on the internet) then I make sure I have a release stating the use and restricting them to other uses. Most photogs don't like that but I have been burned so often that if a photog really wants to learn and better himself, he is usually willing to comply.
Hope this helps...best of luck to you.
