Our our January 2004 Mariner cruise, we signed up for a morning bridge tour and it was cancelled 3 times due to rough seas or foggy weather! Late one afternoon, we received a call that they were waiting for us to join the bridge tour. We had not checked our messages on voice mail. Alan rushed up to take the tour. I was getting ready for dinner and missed it.

Also, our traveling companions took a navigational course one morning which was located on the bridge.

But, the bridge was not "open" while at sea. We were required to sign up for the bridge tour.
