You don't need to carry your passport with you unless you do an excursion in Skagway, that takes you into canada. The Yukon Train for example. You'll still have to take it with you in case something happens and you need to get home.

Princess is has relaxed formal night. Men don't need suits or jackets. When we went in 2019, I wore simple dresses and hubby wore button up shirts and slacks. You'll see everything from ladies in skirts and bosses to formal dresses and men in nice shirts and slacks to suits and ties. Dress like you were going to a nice dinner at home.
