O.K. If my math is correct the opinions about this company are split almost right down the middle. We would like to visit Mt. Vernon. The 10:30 start time for this company's tour is very attractive to my sleepy-head wife. Do any of you experts have any experience with this company, or other Mt. Vernon tours. I would love to see this historical site as trouble free and comfortable as possible. We will be in DC Oct 5th thru 8th. Thanks Tripadvisor for all your great info.
