I wish I had better info on the source, but a few years ago I called up to Door County to ask about trails and conditions. It was a resort from an old trail map that I had. The guy on the phone told me that most of the trails were closing down and dead ending and the system was in bad shape. He really made things sound bad, and I actually believed him, so I avoided the Door. A few years later, I looked into it again and found that the trails in Door are doing just fine and the only issues are typical snow related. I wish I could remember who I called but I always wonder what his problem was.
I don't know if trails go into Sturgeon Bay, but Cherryland Motel is clean and convenient.
