The easiest way would be to transfer your package over to a travel agent that will make the calls for you. Dreams Unlimited is a good one to use (board sponsors) and they can let you know exactly what needs to be done for them to take over the ressie. Then they'll make all the calls for you!

Assuming your with BT it's not that expensive to phone the normal number (from the uk 001 407 939 3463) it costs about 10 pence per minute in the evening and takes 15-20 mins to get through and book 2 weeks of ADR's
