My family of 9 decided on using Susie's service a week before we arrived and a great decision it was!!
Susie took us around to the sites we pre selected and provided excellent knowledge of the history and area during our drives to the sights. She showed us popular tourist sites but more importantly the off the beaten path locations that we would have never seen otherwise.
Our family ranged from 2 - 67 years old and she was able to accommodate all of them. My 2 yr old niece had such a great time with her that the next day she was asking "where's suzie". She equally was able to make it memorable for my mom/mother in law/father in law who loved the stops especially the last one!
While we booked one week in advance, I would suggest doing it much sooner to ensure you get the tickets you need and she can secure an appropriate vehicle to accommodate your group.
Great tour that I recommend to friends visiting now.
