Just stayed in St regis bal harbour , booked using combined points from my and my friends account . Spoke to marriot they said my name was put on reservation . Even got a text confirmation . When i got to the front desk they said since account is not in my name it needs to state gifted. There were 3 other people in lobby with the same issue.Had to stand there waiting to speak to marriot 800 number. Was resolved after waiting for a while for marriot to change . Just make sure to call ahead
