If a FF trip is scheduled which avoids Eilidh's birthday, that's one hurdle crossed for me for sure  
 
But if it's June, next thing I bet is it covers Lisa's instead 

  I could pack her off to some health resort though couldn't I !!
But I regret it will still remain a costly trip...although a strategically selected pax could lighten the load I guess...
Alistair, where are you...!
Will watch with interest.  Hope Mas du Clos is on the list.  That might just swing it.
