Just got off the Wonder two weeks ago today (painful memory!!). Don't know if it makes any difference, but the Wonder might dock on either side of the terminal. We boarded and deboarded on the left side of the terminal, as you face it from the street. Our hotel overlooked the other side and I was hoping it would dock there for a great overhead photo, but noooo! I have seen pictures of it docked on the right side.
Awesome time exploring a small part of our biggest state.
