With regard to the Gx (eg. G1, G2 etc.) offer codes, must they be entered at the time of reservation or can they be added later, such as through phone reservations?
Hi Danger
Yes you can easily request these bonus offers on existing bookings via phone or by emailing GPP - they have always happily added them . They will usually send a confirmation email as well so on the odd chance you don't receive them from the hotel just forward the email and points you shall receive!
Cheers
