I have a Marriott Explore Authorization Form that was offered to me by a friend. Can I use this form multiple times until it expires, or can it only be used a single time? I keep getting different answers from different agents on the phone at Marriott, which is making me uneasy. I have 3 different bookings at the same hotel this summer and want to be sure they will honor the Friends and Family rate for all 3 bookings even though I only have one form. TIA !
