Hi printed mine for the first time. I did mine in color and laminated them at work. I'll put them on with zip ties once I get to Miami.
I do have one complaint and that is the fun pass web site. My god what a hassle. The airlines changed my flight so when I went in to change the information the site kept reverting back to the old flight number. I called Carnival and they said it was a "clich" after three times of doing what they told me to do I finally made them correct the issue.
All in all the web site isn't bad to navigate.
