I'll be following with interest, I'm cruising to New Zealand in January.
A couple of questions come to mind
Is there any entertainment that needs to be booked? (like comedy club)
Are there any dark spots to do some star gazing?
Normally if you're booked A to C via B on the one ticket the airline will look after you if you miss the connection. If you were given seperate tickets on seperate airlines I would be worried about having a backup plan.
In recent weeks there has been a relaxation in a number of protocols for public transport and isolation for example. Who knows what will change before Spirit gets here?
Currently, the NCL Spirit alternates between Alaska and Australia/NZ with a bit of Pacific inbetween. I'm sailing on her in January. With the way other protocols are being loosened I wouldn't be surprised if they get relaxed before.
