On Friday, we talked about getting to BlizzCon by air. Until teleportation technology is invented (and not deadly) or "The Big One" hits causing Anaheim to become coastal, the only other two ways to get to BlizzCon are by train or car. (Edit: Ok, there is the bus, but yeah, ugh. AishaLove is right. I can't recommend it.)
Trains: Anaheim is a stop on the Pacific Surfliner route. Amtrak can be pricey, but with a membership in AAA and a watchful eye on their specials, you may be able to come up with a price that is comparable to flying. The train stop is just down the road from the Anaheim Convention Center and is close to most of the hotels. Of course, trains take much longer than planes, but the trip can be part of your vacation fun.
Automobiles: The Anaheim Convention Center is right off the I-5, near the Harbor Boulevard exit. You all know how to use Google Maps or your favorite mapping program to find the best directions. If you are thinking of renting a car or making a long road trip, gas prices will probably continue to go up throughout the summer, so you need to calculate mileage and worst case gas costs into your budgeting. Also, be aware that the greater Los Angeles area has ridiculously long and stressful rush hours. Try to avoid arrival into town during the hours of 7am to 9am and 4pm to 7pm. When there are accidents, expect those hours to expand and the freeways to turn into parking lots. AM radio has a few stations that keep you up to date on traffic and this traffic site is invaluable to check when you are getting close, if you have the technology.
Anaheim is a pretty safe place to be, but there are many pockets of nastiness in L.A. proper. Getting off the freeway in a place you don't know is not recommended. If you can avoid the city altogether in your trip, it would be best for your stress level and your personal safety.
