Hi Lucia,
I'm Ann, and also doing the Boston add-on for 4th October.
When I phoned up a few days ago there were 29 doing the standard trip, plus 4 of us doing the Boston add-on.
As I'm also flying from Heathrow @ 08:30, I'll probably see you in the lounge.
Not long to go now - I'm looking forward to it!
Ann
