Amy, do you feed them twice a day? I found that this helped a lot. They were loading up on food at the end of the day, which would make them thirsty, which in turn would make them want to pee (or wake me up for a drink of water, which pisses me off too, lol). We also now keep our bedroom door closed at night so they do not have access to water and they cannot leave the room to go wandering around to pee. They seem to consider the bedroom their "crate" and do not like to pee in there. They'll go in the bathroom when an accident does happen.
I also used to give them cheese on their food and I decided that it could be too salty for a small dog. Now I don't give them any topper (causing a lot of sad looks and general turning up of the nose, even by Teddy) or give them a very small amount of organic canned food...like a couple small spoonfuls each. If I want to give them something saltier, like salmon or mackerel, I'll do it for breakfast because they never have accidents during the day.
Honestly, I think moving helped as well, even though that's not really a great idea to spur potty training, I know. But we totally broke the routine, broke the area they went to pee in forever, and put them in a new environment.
