Sorry, sboone, just noticed your actual question was about *not* blocking rooms... Hm, I don't know if they'd be open to that, since their prices seem pretty reasonable already (especially compared to other hotels at the same level on IM). They did seem pretty flexible with wedding arrangements, but I bet you would find your prices hiked up on the little extras if you didn't book rooms through them-- you notice they don't post prices for the "extras" online. Still, I can't say with any certainty, so, guess I'm not much help after all! But the Reservations Manager's name is Edgar, and he is who you would talk to about it. Have a great time there in December, you will love it!
