It's also important to consider how much time the ship spends inside Glacier Bay and where it goes. GB was a full day of sightseeing on my recent Crystal Harmony cruise and we sailed far up Tarr Inlet for a close up look at Margerie and Grand Pacific Glaciers. Then we sailed all the way to the end of Hopkins Inlet for a close encounter with Hopkins Glacier. According to the park rangers who gave us the onboard lectures, this last is one that few ships have a chance to visit.
