Thank you Cat.
I appear to have had success with the last option

Have just managed to reserve the 2 tickets for the AP birthday holders as well....even though Disney Guest relations have just emailed me stating that it's not possible to reserve tickets, as they must be purchased in full beforehand!
Do you think Carrefour are likely to send me a confirmation email?
