Hyatt - 78 nights (+ 7 free/award nights)
SPG - 38 nights (+ 2 free/award nights)
PC - 2 nights
Barring any unforeseen change in the promotional terrain, I anticipate a major drop in SPG nights for '11, with PC taking up the slack.
That said, if GP doesn't get its act in gear for a Q1 FFN or other ambitious promo, I anticipate that PC might take away from Hyatt's nights, as well.
