Do you have your heart set on the White Mountains area? Just wondering if you might consider Canobie Lake Park or the Lakes Region. They have Weirs Beach, waterslides, arcades, beaches, mini-golf, etc. A lot of the stuff in the White Mountains is geared toward youger children, i.e., Santa's Village, Storyland, etc. My kids are starting to get too old for Storyland and we will probably end up going to Canobie Lake Park this summer instead. Have a great vacation whatever you decide to do. It sure is beautiful here this time of year.
