As a first time cruiser with my husband, we had a mostly positive experience with the Star Princess.
Yes, there were lines, but not horrible. We arrived by noon as we figured let's just get started. First step - drop off luggage, go to enter line to get to security, up the escalators, go through security, go into another line to get cruise cards, from there, go enter into a line to get on the boat. Once on the boat - smile - time for a photo. This process took about an hour, lines were always moving (think Disney with the creative line development). Enter elevator, go to your floor, see room, and off to get lunch. For lunch, we went straight to the buffet, we didn't see that pizza and burgers were available if we would've turned right vs. left on the deck.
Lemonade is provided at no cost (we didn't learn this until day 4) - not all bars have lemonade, but those on the lido deck do.
Luggage was by the room by 2-3pm, unpacked, and explored some more.
Ice cream -
Cones are at no cost, milk shakes cost $2.50.
Evening Dining -
We did timed seating at 5:30pm so we could see the shows at night. First night, there was a line as the waiters show you to your table (listed on your cruise card), after that, you just walk to your table. Waiters do try to upcharge with bottles of wine (which they will hold for you and bring back to you the following night). Offered specialty coffees and tickets to wine tasting ($25/per person).
The Crown restaurant was very good, you do have to pay the upcharge of $25/per person. Food was excellent.
Ports of calls -
Expect lots of jewelry and t-shirt shops. Onboarding and off boarding were pretty uneventful. Lines to get food on the boat before exiting to Juneau started up around noon or so.
Trip was very good, we would do this again (also, balcony was worth the charge, weather was nice, we used it quite a bit). Only hiccup occurred on last day on board. We received our invoice and we were charged $25/per person per bag for the Ez checkout (you put out your luggage the night before, and you see it again at your home airport). Both of us were not to be charged by the airlines for our bags due to frequent flier status. When we were charged, went to see princess personnel, they said I had to talk to the airlines. I spoke with the airlines, they said they didn't charge us, had to speak to princess. By this time, we were off the boat. Did send an e-mail to princess the following day with verification of frequent flier status (photos of bags listed as premier members), and 2 days later received a call from princess that we would be refunded the expense. After looking at the travel boards of similar situations, I would really highlight on the EZ checkout documents if you are exempt from paying luggage fees. Others even printed out information in advance, and stapled it to the documents to avoid the same erroneous charging from occurring to them, and the run around of who to seek reimbursement from.
