I've been taking my family to the Oliver Lodge in Meredith for the last 4 years. The owners, Herb and Lydia Oliver are really nice as is the whole compound that they run. There are a couple stand alone houses (we stay in the Ice House). There is also a huge main lodge with a north and south wing. They can accomodate large groups and family reunions I think are their specialty.
They have boat docking, canoes, kayaks, and 2 nice sand
y beaches. They have a pretty good web site. If you google Oliver Lodge Meredith, it will come up. Good luck finding a place, Lake Winni. really is the ultimate family vacation.
