Dave, I'm under no illusions that is was just a ploy to get more bookings
Although I didn't realise you could mass mail through the AW system, I assumed she'd had a busy morning - having said that it was a personalised message, I doubt you can do mail merges in AW.
But it did remind me it was about time I saw her again, tried to book for next week and she says she's got her sister visiting so she's only doing duo's - doesn't appeal to me I'm afraid.
