This is the place to discuss the episodes of the Comic Book Page podcast, the Comic Book Page website or pretty much anything else of interest to the Comic Book Page community...
If you go through the hotel site or other sites, it will tell you the hotels are booked and full but, I believe, Comic-Con negotiates to save a block of rooms which is what will go on sale. Unfortunately, I've been hearing horror stories about that process for a few years now.
I booked my room about a month ago at the Marriot that is attached to the convention center. It's alway better, for me, to try booking a room through priceline.com or another booking site. But yes, there is a block of room that are set aside for SDCC, but I'm not willing to wait and risk getting a room that is miles away.
