I saw on the Nestie board that you're going to Maine - we are going this summer, with DS! Are you taking the kid too?
Also, right after I last vented about DS's 5 am wakeup call, he started pushing it back on his own. For the past couple of weeks he's been waking up around 6:30. Ah, bliss, and no sleep training necessary. I think my new answer is to complain on the Nest and see what happens.
Hope you've had similar luck!
