Ruby on Rails Bootcamp Training

Can anyone recommend good bootcamp style training (at least a week,
ideally 7-10 days) in early 2012 ?

I am happy to travel anywhere in the world but need to book a class
soon that will definitely run and most of the classes I have found
like Big Nerd Ranch (which looks excellent) don’t confirm until 30
days before the class is due which is just too late for me.

Any pointers and reviews of training classes in the States will be
gratefully appreciated!
