Thanks for feedback.
Church Landing Inn and Wolfeboro Inn are two of the options I've been looking into, but Wolfeboro Inn can only offer standard rooms, not lake front. We reckon if we're gonna stay on the lake, we may as well be able to see it!
We drove to top of Mount Washington last time - exhilarating and scary on way down!
We do have a car and intend travelling around a bit.
Any other areas around the lake (other than Meredith and Wolfeboro) that we should be looking at?
