thank you Amy.
I was so worried by your post that I rang your office.
I was told that 6 were doing the add on to Singapore and the tour would definitely be happening.
I checked times of flights again and I was told that I am booked on the 10.00.am flight from Heathrow on the 16th with a 2pm flight from Manchester the previous day.
I hope the office are correct and you are wrong.Your website is giving wrong times for this holiday.
