You will probably be about an hour to Mount Washington, Conway and North Conway (outlet strip capital of NH) and some beautiful sight seeing. You can go to the Yorks, in MAine, 2 really great beaches. Ogunquit Beach is north of the Yorks and south of Kennebunk. ALso Kittery is south of the Yorks, about 7 miles and another outlet area, BUT there is NO SALES TAX in New Hampshire and ther is in Maine, so if outlets are your thing, go to Conway.
Also, you will be about 45 minute to Lake Winnepasaukie, there is a great beach there (Weirs) and the Moter Vessel Mount Washington goes all around the lake day and evening.
