The press release on parent P&O's web site (http://www.p-and-o.com) indicated that the transfer will occur in the Spring of 2002. I expect that she will complete the cruises that are currently scheduled.
We were on the Star Princess for its last season with Princess and the service was great. The fact that the ship was leaving the Princess lines did not affect anything that I could tell. The only thing that made me know something was up was the fact that people were on the ship measuring for the refitting for P&O. I had to ask the bartender what was up and he told me they were measuring to change the ship. They were in no way intrusive or interfered with any activities, so I assume the service will remain the same as always on the Crown. With the new ships being built for Princess I am sure many will stay working with the line and do not want to lose their jobs.
