Thanks for the input. I'm CP so blackout dates are not an issue. With respect to flying back on Nov. 29, that was a bit of a misstatement on my part. The 30,000 award is for a flight that originates 11/28 then overnights in Philly before continuing on 11/29. So you don't get any extra time on the ground in the islands, just a night in a hotel near PHL. Wheeeee!
Still mulling this one over...to burn 140,000 DM or not to burn them, that is the question!
