Wimbledon and the Queen Mary 2 June 2004

My wife and I are flying to London on June 21st (2004) and staying at the Sheraton for 4 days. We have "debenture" tickets for 2 days at the Wimbledon Tennis Championships. Could someone tell me what "debenture" tickets are please. We then will cruise on the new Queen Mary 2 to New York for 6 days. While in NY for a few days we will visit the U.S. Open Tennis Center. We then will fly home to Vancouver after this magnificent 10 day venture. What a combination! Wimbledon Tennis Championships during its second week! The newest, biggest, fastest, and most luxurious Cruise ship! Tennis and Cruise enthusiasts from all over North Amerca are going to be part of this venture. If any of you would like to join us,respond to this thread or email me for more more details.
