I was going to order hoppers from the website, but I waited a little too long and I wasn't sure that the passes would get to me before we left. The "tickets by phone' suggested DS. They were no help at all. Maybe it is because I live on the east coast, but when I said DL to my local DS cast member, they had almost no info at all, no knowledge of specials and said they would have to order any tickets/passes that I wanted.
I used AAA to buy my hopper passes-- very good price, but the representative at AAA said that kids only go free on the hopper passes if you live in a certain zip code in CA.
