Does anyone know about the special code for Amtrak's 2 for 1 deal? We're wanting to take the coastal train from San Diego to Anaheim. I noticed someone was selling this code on Ebay. I would need this for 2 adults & 2 children.

Are there any discounts available to the San Diego Zoo? We want to be sure to do the Skyfari. Does that cost extra? Are there special tickets we should purchase?
