Hello everyone! We have just booked our 2nd cruise, and our first with Princess. We are plannng on taking the Mexican Riviera trip on Jan 20, 2007. I am wondering what kind of weather to expect. Has anyone taken this trip close to this time of the year? Will it be warm enough to swim onboard in the outdoor pools or lay out in the sun? Porting from LA should be cool but hoping the at sea weather will be nice and sunny and warm. Any feedback would be great!
