Hello - I was trying to use one of my certificates today. it was set to expire today, and as I was trying to make a booking using the certificate, it was literally dissapearing in front of me.
In line with other hotels offering similar vouchers with expiration dates, should it not be valid until the end of the expiration day?
If not, I suggest Marriott publish the expiration the day before it actually expires. That would clear any confusion.
