I appreciate the information thank you very much. Hopefully, I don't get lost, I seriously got lost the first time I was on the Imagination. Couldn't find my way to one of the lounges and missed half of the presentation. I think this time I will print out a layout of the ship beforehand to get my bearings somewhat.
