Our #1 favorite part of the cruise was taking the Tracy Arm Fjord catamaran shore excursion. This is a limited-seating option, so you should book early if it sounds appealing to you. But if you go, DO NOT BOOK AN AFTERNOON SHORE EXCURSION IN JUNEAU. Our catamaran spent an extra hour in the Fjord and then it took 20+ minutes for the crew to properly align the catamaran to the ship so people could transfer back to the ship. By that point, we were 1-1/2 hours later than we were supposed to be. Many people missed their afternoon shore excursions. We had not booked an excursion, so we were OK. We went on shore in Juneau and immediately went to one of the MANY tour kiosks right next to the ship. For only $20 round trip, we were taken on a bus to the Mendenhall Glacier where we had ample time to hike to Nuggett Falls.
DO NOT BOOK the Skagway White Pass & Yukon Railway shore excursion (SK01). Limited narration which is repeated word-for-word on the way up and again on the way back. Also, you have to step outside the train car to get a good picture but they have no speakers outside the train, so you have to choose -- do you want to take pictures or do you want to know what you are passing? You can't do both. third problem with that excursion is that they never let you off the train. Afterwards, we spoke with other passengers who took an excursion that was van/bus in one direction and train in the other direction and that seemed to be a much better tour. That said, the scenery was beautiful.
