Wish I could give you better info, but I don’t go to the shows. It seems to me that you won’t have a problem getting a reservation if you do it a couple of days after they open up.
Ignore what she said. Check in between 21 and 3 days before sailing. The only reason to stay up and check in at midnight is to get the first check in time at the pier. You also might make show reservations but they are not going to be gone the next morning at a reasonable hour.
Check the Bar Harbor Port web site, not some third party place that is clearly incorrect. Additionally, with the limitation on ship sizes it is doubtful that any NCL ship will be in Bar Harbor in 2025.
Just like any other extra you buy, if you don’t go on the cruise for any reason you get a refund of the costs for extras. No penalties are applied to these types of purchases.
If they’re platinum or above their reservation window opens at 125 days. If they are in the Haven it opens at 130 days.
Yours will open at 120 days.
They can make reservations for four and you don’t have to worry about anything.
