Millenium in Alaska - how many formal nights?

[nutty nurse gladys]

Really looking forward to our first trip to Alaska next month. Doing land tour first then 7 nights on Millennium...........roll on. Just wondered how many formal nights there will be on the 7 night cruise We have done many many cruises over the years and love to dress up for the formal nights with tux etc. However this time hubbie is thinking of just taking jacket and tie slightly less to pack when considering weight etc. would there be just one formal night or maybe two?

thanks.

many thanks, that's what I thought but wasn't sure if Alaska was less formal as I have heard some say.
