Thanks everyone. This is great to know.

This must be an incredibly stupid question because I haven't found the answer anywhere. I need to preface this by saying that I have such severe anxiety since a TBI I can actually have seizures and I need answers to kind of strange questions before I can even begin to enjoy myself even in everyday life. So something like this is driving me crazy because no matter how I word it I can't find the answer. We're a couple from Iowa going on an Alaskan cruise in either September 2021 or 2022. Probably this year since the one that I want is, right now, around $1000 pp for a balcony cabin. The one I'm looking at that I would like to take depart and arrive in Vancouver. Now here's my question: Since this cruise departs and arrives in a Canadian city if I choose to tip extra should it be Canadian or American dollars? This is our first cruise and our first vacation/10 year anniversary/really late honeymoon present to ourselves. And like I said with my severe anxiety I really don't want weird things like this ruining what should be an amazing trip. Everyday cruise etiquette will be enough that I don't need off-the-wall questions like this hanging over my head. Thanks, Leah
