I have two nights booked as an award reservation. The two nights are however booked as two seperate reservations with seperate confirmation numbers. Reason for this is that SPG didn't have the second night available for a standard award when I originally called so I only booked the first night. Second night became available today so I booked that as well. Questions is if I should call SPG to combine the two nights reservation or just leave them seperate? Will it make a difference for a possible SPG Platinum upgrade?
