We cruised with NCL in 2018 on the Spirit and had a stellar experience. This year on the Star, we were a little disappointed for a few reasons.
The ship was recently refurbished and we appreciated it - it was like brand new in many aspects. We really appreciated the updated staterooms (particularly the USB ports next to each side of the bed and the real hairdryer!). However, the layout of the ship is not intuitive and just didn't feel like a home in some ways.
First, each stairway/elevator should be a vertical path to access ALL floors, but this was not the case on the Star and it was confusing.
Second, NCL could put signs at each elevator/stairway to show which side is Port or Starboard, since the colored doors aren't visible on each floor.
Third, there is NOT ENOUGH seating for the buffet and it was a huge problem. Too many 4-tops mean wasted seats. NCL needs more 2-tops, more seating in general, and it was disappointing there was no outdoor seating for the buffet (unless you wanted to walk all the way to Spice H2O).
Finally, we were very disappointed there is no forward viewing lounge inside.
As for the crew - the stateroom stewards and bar/restaurant staff were great on the Star, but the Shore Excursion staff were not knowledgeable about the details of their tours. In particular, one of the ShoreEx managers was rude and condescending to us, to other guests, and to fellow crew members.
In addition, we interacted with numerous people on the Guest Services desk and on EVERY occasion, they either did not know the answer to simple questions, or they gave us incorrect information. or they gave us conflicting information. It was VERY frustrating and makes NCL look incompetent and unprofessional.
Finally, the Upgrade Advantage program is VERY frustrating. NCL absolutely must be more clear and transparent about how the program and process works. We got conflicting information every time we called or emailed NCL, and their website doesn't provide enough clarity. It caused A LOT of frustration and angst beginning at 3 months before our cruise, up to 48 hours before our cruise, which was NOT enjoyable. If we could've gotten more accurate information about the process from their website or call center, it would've been better.
I'm sure many people complained to NCL that the embarkation process at Tarragona was an absolute disaster. I'm VERY upset we had to rearrange our plans AND PAY for the cost to travel from Barcelona down to Tarragona, only to deal with the mess of an embarkation day.
I'm not sure what the solution is, but it would be nice if there was a better process to tender, other than having to wait in a line for 3 hours to get tender tickets (guests started queueing at 7am for 10am ticket distribution for Santorini). That's not a relaxing vacation.
The WiFi on the ship was also a disaster. We paid $350 for the unlimited package and it only worked about half the time, and when it did work, it was horribly slow. I get it that we're at sea, but NCL shouldn't ask their guests to pay that much for a sub-par product. Fortunately, the Internet Manager realized the issue and gave us a small credit to our account, which we were happy with.
Overall, we still enjoyed our cruise and we do plan to cruise with NCL again next year. This was an absolutely fabulous itinerary, visiting so many amazing ports.
