We had a 4 hour tour with "At Your Service " and it was everything one could hope for: interesting, colorful, entertaining and memorable, much of it due to our wonderful guide, Bill. Bill was funny, knowledgeable and always willing to accommodate us when we wanted to stop for pictures, which was often. Bill is from Bar Harbor so his wealth of information regarding the city, the Park and the locals is immeasurable and his stories are amusing. Acadia National Park is truly awesome and we were so blessed to experience it on a beautiful fall day; the air was crisp, the sky was blue and the colors were vibrant and breathtaking. I highly recommend this tour company, this tour guide and the sights of Bar Harbor and Acadia National Park, which together combine to create an amazing day of treasured memories.
