Since this is fairly new, I haven't been able to do it myself, but you get into the Princess web site, then go to "captains circle". Scroll down to the end of that page and there is a place to click into that you can sign up and set up your ship account. You will need your booking number that you should have. Good luck and hope you get all the excersions you want. We were able to book excersions prior to sailing earlier this year and it worked out great, tickets were in our cabin when we got there.
