I reserved the larger caboose for my husband's 60th birthday when you order the caboose you must begin the ride in Sunol. Before the event I found the staff very helpful. They responded to all my questions within a few days.
On the day of the event, we were given the block of tickets and not asked to pay until after the event. I reserved the 12:30 train, and was able to bring sandwiches and drinks on the ride. There was a small table and counter to place these items easily.
Afterwards the group gathered at the picnic tables next door to take a group picture.
A relaxing a fun Sunday adventure!
