I've read a lot about the JFK Assassination, so booked the full tour. It included entry to the Museum on the 6th and 7th floors as well as the Oswald's Rooming House.
We got a great overview of Dallas and its beginnings, starting with the JFK Memorial, stories about the founder of Dallas, Dealey and the plaza named after him.
Orlando was our competent, friendly, and funny guide. He was compassionate about his customers and helped them in and out of the van.
The van was about a 15 seater, but we luckily only had 12 (plus the driver). There were quite a few stops with invitations to get out to take photos. At one location, the group decided NOT to get out. It was a cool and windy day.
