I was unable to book to book two different SPG hotels in HNL on various dates using Marriott.com. I was signed into my PP account, but when I tried to confirm my selected room, I received this error message:
We're unable to locate this Starwood Preferred Guest® account, or you have entered an invalid SPG number. Please re-enter or remove your SPG number, check that the last name you have entered below matches the name on the account, or contact us for assistance
Any tips or advice?
