Hi all: We are traveling to Buenos Aires, and are really hoping to upgrade to a suite for our four-night stay. We called the Platinum 800 # (neither of us are Diamond) and -- after talking to the helpful agent -- we have concluded these are our two best options: 1.) Upgrade to the normal rack rate, which will add about $650 total to our stay and will cost us 24,000 points for a suite upgrade (6,000/night). Our reservation for a deluxe king is currently booked via my partner's employer's corporate rate. 2.) Stick to our current rate for a deluxe room, and inquire about upgrade options upon check-in. The helpful woman at the Platinum # said "or you can pay the higher rate and use points or you can just hope for an upgrade at check-in. That happens a fair amount, but I obviously can't guarantee it." We do not have the 108,000 points we would need to book a 4-night free night stay at the suite level (We have about 50,000 combined -- 35k in one account and 15k in the other). Any suggestions would be greatly welcomed.
