We use Grace Limo for all our airport trips to Boston and Manchester. We've also used them for special events around the lake. A few times they've picked a group of us up in Gilford and drove us to dinner in Wolfeboro and back. When you book them for dinner you get them for a block of time because they wait for you to finish dinner. I highly recommend them. They are a second generation family run company so customer service is very important to them. Here is their website:
