We were on this cruise last year and it was amazing! The Haven observation lounge is fantastic. The weather was a lot warmer than I expected it to be, so I ended up buying a couple of lighter-weight shirts in Juneau.
We didn't do any excursions except whale watching in Icy Strait Point, which was a lot of fun. We have family in Sitka, and on previous visits there (not on a cruise, I mean) we have gone to The Fortress of the Bear and the raptor center. I liked both. We went to the Red Dog Saloon in Juneau (husband stopped there many times in his 25-year Coast Guard career and wanted me to see it). Victoria was an absolute madhouse. If I had to do it again I would've just stayed on the ship.
Mario is the best Haven bar waiter! I don't know if Jersey Boys is still the show on the Bliss, but we saw it and loved it.
We got to the port about 10:30-11:00 and the Haven waiting area was standing room only, which wasn't ideal. We would probably choose a later time if we went again.
Have a fabulous cruise!
