Many thanks for this tip,
AJLondon ^ ... I just switched as well.
Strange thing happened though. When I cancelled my HI Express reservation, the confirming e-mail had the IC George hotel name and reservation number

but the Express room description! A quick phone call to reservations confirmed that all is well, however.
Lesson learned : when making and cancelling Priority Club reservations, do not have two instances of Internet Explorer open!
Looking forward to seeing everyone on Sunday
