I am very interested in the YR cruise and tour. We are thinking of the uniworld 21 day tour, which includes 6 days on the Victoria cruise line. I have taken the Columbia River tour and understand the difference in Ocean cruising and River cruising. I have concerns after reading cruise critic boards and hearing of disappointment with uniworld. We're booking through AAA and our agent says they have not had any problems with uniworld trips, but its still a worry. We would really like to hear from anyone who has used uniworld or done a simular cruise. Thank you.
