We were on the southbound Jewel sailing July 4th. I usually pre-purchase one of the bottled water packages thru NCL, your cabin steward will deliver it to your stateroom on the day you sail if you wish.
We went to the "Velvet" show in the theater, not at all impressed. Did really enjoy other entertainment in the bars/lounges though, our favs were "Glitz Duo" and Melvin on the guitar, outstanding! They were in the Magnums lounge, Bliss lounge and Atrium areas for the most part.
Le Bistro was very good, didn't go to Teppanyaki. Cagney's was pretty good as was La Cucina. We also enjoyed the MD as well as the buffet. Don't know about upgrade bids, didn't do that. OP answered the Seward question. Ship docks in Vancouver at 7:00am, you can begin disembark process as soon as the ship is cleared by customs and port authority.
The ship guest capacity for our cruise was approx. 1030 guests according to crew members. So, 40%ish. Was great! Alaska from the cruise ship vantage is beautiful, very unique! The evening sailaway from Seward is gorgeous. At least if was for us. We had clear skies, soft seas and a superb sunset. The massive glaciers are incredible. The Inside Passage is stunning.
Enjoy your crusie!
