If you don't mind I'll will tag along with you on this thread. We have the same cruise, but we are going on 7.21.06.
I am interested in tours at the various ports. I am debating on doing some on our own and others with Princess. Our son and his wife will be with us (about 30 yo) and he is not bothered with doing things on his own. So we can tag along and let him and his wife be the "tour guides".
