Look at vrbo.com, they list properties that are owned and people want to rent out, mostly condos. Sometimes the big chains-hyatt, starwood etc., will have good deals-like 2nd night 50% off, and some of the locations near ski areas have kitchens, which are so helpful with kids. I would recommend going to CO or Utah, the snow is better and there are many more resorts. The NE is very icy...
