Very interested in Full Day Amalfi Coast tour on May 10, 2020, coming in on Crown Princess. Where does the boat tour stop for us to go ashore and how long? Is there a bathroom on board, or shade? Will there be time ashore for lunch? We have friends who would likely come along, making it 4 people. Can they sign up separately, and you hold their spots, if we sign up? Should I try to get another couple from Cruise Critic Roll Call? Or will you fill it up to 6 people? Sounds lovely! Thanks!
