As I was planning our Fall trip and looked up the Anaheim convention center I discoverd there will be a big conference going on while we are there. This got me thinking .....How much do conferences really affect Disneyland crowds? This particular one during Sept. is for the National Safety Congress and expects about 16,000 in attendance and is on a Mon, Tues & Wed.

Here are my questions:

Does anyone think this conference will affect Disneyland crowds?
What conferences do make for bigger crowds i.e cheerleading ?
Do any of you check the Anaheim Convention center whan planning a trip?

Thanks for any help or input :).
