Bob - know what u mean, was asked a few years back to do the same, people dropped out, wanted to changed dates for travel. AHHHHHH
In the end took a hit on cost, put it down to experiance. Thats why I like I like planning for 1!.
Mind you this year, sorted out tickets for some people who I first went with, but they offer to pay the amount straight away.
All I do this year is meet them on site.
Mind you, they are off on Sunday am (10ish

) so may be over on Sunday night for any curry left.

See u all down there on Thurs.
