Not to my knowledge. You just have to go into the "Captain's Circle" page of the web site (by clicking on "Captain's Circle" on the menu in the upper right corner of the home page) to get to the link to the booking section. This link is the words "click here" in the sentence that says to "click here" to book shore excursions, etc., at the bottom of the Captain's Circle page. When you click on it, the site will ask you to enter your name and your booking number, then it will display the booking record. Once you get the booking record, there's a button at the end of the booking record to book shore excursions and a menu across the bottom of the page to enter immigration and emergency contact information, special dietary needs, etc.
