Are their molars coming in right now? If not, I wouldn't plan around that. They're actually the 2-3yr molars, because they can come in anytime in the next year. All of my kids started getting them around 2 1/2 - 3.
I was going through the same thing last fall with my twins, and I posted this thread about it: Nightweaning and cosleeping, please help!
Reading through it might help you, I wrote in there what I ended up doing. The difference is that I have a partner who was able to help me a few times, but it would be doable on your own, especially if you don't have older children.
Good luck, and hang in there! It's really tough to have your sleep disturbed for so long.
