Hi Debbie,

No, you can email these details in to us in fact, if you visit this page below and fill in the form here it will go straight through to the relevant department...

Complete your details (including booking reference number),select "question post-booking" and then included the emergency contact details in the "Your Enquiry" box.

Kindest regards,

Julia

I have my booking information and you are asking for Emergency contact details, is this something I can e-mail (obviously to a different address to this one) or do you require a paper copy to be posted to you?Thanks Debbie
