Exited/Nervous for in the trip

What I am most exited for in this trip is to do all the different activities especially going on the duck tour and getting on the ferry to go to the San Juan Islands. I'm nervous because of the times and I think that I would be late to most of them or I might not know where some places are going to be after the first day. In other words I am looking forward to this trip because I am hoping to have an amazing time.
