My wife and I are flying to London on June 21st and staying at the Sheraton for 4 days. We have "debenture" tickets for the Wimbledon Tennis Championships for 2 days. Can someone please tell me wht "debenture" tickets are. We then will cruise on the 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. Tennis and Cruise enthusiasts from all over NA will be part of this venture. If any of you would like to join us, email me or respond on this thread for more details.
