Looking for Answers about Norwegian Dawn?

After a lifetime of seasickness, I have found a perfect solution, for me. I take one Bonine tablet, this is non-drowsy, the night before I leave on the cruise, then every day I take one in the AM and one at night. It seems that getting it in your system before getting sick is the answer.

The balconies have connecting doors but the doors are locked with no keys for the passengers. The doors are kept closed for safety reason (not sure how) but if you explain to the cabin stewards that you have friends/family in the adjacent room, I'm sure they will be happy to open it.

NCL only allows wine and Champagne to be brought aboard the ship. They charge a corkage fee for the bottles. Beer and other alcohol are not allowed. Onboard the ship, you can purchase the beer in buckets and you can bring them back to your stateroom.

It's better to use a credit card rather than a debit card. NCL puts a hold transaction on your card and based on your usage they may put multiple holds.
If you exceed your limit on your debit card, you could incur additional charges from your bank.

Not at all! Booking an excursion through the ship just gives you certain guarantees and assurances; such as a tour that has been reviewed by the ship and is held to their high criteria, also, should the tour run late, the ship will wait for cruise sponsored events; if you go off on your own it is your responsibility to get back on time.
There are advantages to both, but either way you should enjoy yourself.

There are hair dryers in the stateroom, not necessarily in the bathroom. Beach towels are provided for your use at the ship's pool or beach excursions and can be exchanged for fresh by your room steward or poolside. Don't lose/misplace them or you will be charged a fee.

The chances of you getting a particular room is slim if the room is already booked. You have to hope that the passengers cancel their trip. If you booked it with a travel agent, you can ask them to keep an eye for that room but ... again ... chances are slim.

The Dawn was launched in 2002.

The ammenities the ship's stateroom is just as in any hotel. Fridge, TV, coffee maker, ice buckets, beach towels, clock, hair dryers, soaps and shampoo.

Depends on the location of the bar. The pool side bars close early in the evening. The bars in the lounge are open late till 1 or 2 AM.
