Welcome to cruise-chat! If for whatever reason Hubbard Glacier or any of the scenic cruising days are cancelled due to conditions for that day, they'll still seek out an alternative. Perhaps Mendenhal Glacier, Tracy Arm Fjord or another spot just as dramatic and beautiful. That's the nice thing about Alaska sailings, there is no shortage of breathtaking sailing option for the scenic cruising days. It's the days at port that are often limited for alternatives. If a port day is missed, it's very hard to replace. Most port stops are at capacity through the short season with the number of lines and ships that now do Alaska sailings.
