Hello Noreen
Welcome to the community. I am on this trip and doing the Yangtze Add On. The last I heard was that there are 26 of us altogetther and 12 are doing the Yangtze. The really good news is that John Drylie is scheduled to be our Tour Manager.
Everyone who has been on this trip says it is very very 'full on' For example, after an 11 hour flight and the clock going forward 7 hours, the first thing you do is go on your first sightseeing trip before going to the hotel.
Should soon be getting the forms for the Visa Application and then the excitement really builds up.
Looking forward to meeting you and the rest of the group at Terminal 3. I shall be staying at Heathrow the night before, but I havn't booked a hotel yet.
Best wishes
Peter
