They're taking reservations online as well (and had been as of at least midnight), but the price was even higher, $199 a night =/
And the hotel didn't say they'd start taking reservations for Otakon, specifically, on the 15th...I dunno what other people asked, but when I called, I didn't even mention Otakon and they told me to try back on the 15th...it's just the day they start taking reservations for August 2008 ^^;
