Matt if your looking for outstanding panfish fishing for the youngsters Rice Lake is the place I'd steer ya. There's plenty of resorts to choose from. Whispering Pines outside of Keene is really nice and close to some outstanding fishing spots. They don't have a beach but do have a nice pool for the wife and the kids. There's a place right down the bank called Anglers Retreat that has a beach but it's not near as nice.
Good luck in your search
