When we arrived at the tram stop we presented the confirmation and ticket printed on line. The operator of the tram stated we had to go to the office for a ticket. I explained the paper i gave him was my ticket. He had a customer aid call their office to verify our ticket. She was on the phone about 15 minutes before they finally accepted our on line ticket. When we ended our Tram tour we were told to take the yellow line bus back to the cruise ship. The yellow line told us we had to take a different line. We had to walk quite a distance to locate the correct line. The Tram Tour was okay.
