Sooooo I got online this morning to see if I could snag an ADR for 'Ohana 180 days today. Imagine my delight when I found a 5:15 time! So then I went to put in the cc guarantee info. It keeps telling me that the information I put in is invalid. I'm frustrated because I double, triple, and quadruple checked. I put in all of the info correctly. And I know the cc is OK...I just bought a book on my Kindle last night. Anyone else have this experience or have any advice for me?
