I will be traveling with my sister, mom and 3 year old nephew to the White Mountain region during the last couple of weeks in July. We will be driving there from NYC. Does anyone have advice on the top things to do with a toddler? (He loves trains!) Also recommendations on kid friendly accommodation would be appreciated. We plan to stay up to 10 days so we have plenty of time to explore and can move to different locations/hotels. Our budget is moderate with some room to splurge here and there...Thanks!
