cruisefanatic, there is a very active roll call on cruisecritic.com for your sailing. AFter you go to the site, click on BOARDS; then click on ROLL CALLS (you have to join to chat or join a roll call, but it is free); then click on PRINCESS; then click on STAR, and then on your date. You will meet lots of cruisers this way. I just got off a 15 day trip on the Regal yesterday, and we had a wonderful and friendly cruisecritic group on board that really got along well and saw each other formally about three times, and informally we met some of the group many more times. Cruisechat is a great site for info9rmation sharing and chatting, but not large enough to meet cruisers scheduled for your sailing.
We are going on the Star to SA and Antarctica in February, so I am eager to know how you like the ship. I know you will love the cruise.
