For the kids, don't forget Fun Spot (
http://www.funspotnh.com/index.html), on Rt. 3 In Meredith, just a few miles past The Weirs (you'll spend hours there -- something for everyone).
Shopping -- outlet malls in Tilton (exit 20 off of 93) only 20 minutes away from the Weirs area.
In Meredith you have plenty of places to eat and shop right across the street from the public docks.
Don't forget, if you are in the Weirs area to stop at the famouos Waldo Peppers on Weirs Boulevard just before Weirs Beach / bridge. Do a search on the forum for Waldos and you will find out what their hours are. Excellent excellent food -- don't miss it if you are in the area.
And if you have time, I highly recommend a cruise on the Mt. Washington, check out their web page for cruise dates, times and details.

Hope you and your family have a great time here !
