I have to agree that Vegas is the logical move. I've heard they have a crazy big convention center there (much bigger than San Diego's) and lets face it, there is no shortage of hotels and places to stay there. As much as I like SDCC, I would fully support LVCC. SDCC has just gotten too big for San Diego and they aren't doing anything to help it. You couldn't find a place to park anywhere near a trolley stop, let alone the convetion center without paying $30+ or being 10+ miles away. The mall over near the hotel circle area was specifically stating no SDCC parking. They have a freaking trolley stop, a parking garage, and they refuse to let people park there? WTF!?! Its things like that that make moving the show somewhere else more appealing. San Diego would be singing a very different tune after they lose this cash cow.
as a vegas native, i completely agree. vegas would be a great place to move the con to. the only problem is that our airport is not an international airport and our city isn't as "family friendly" as san diego, but we hold some of the biggest conventions in the US without inflating prices 300% like san diego.
