I bought Southern California CityPass booklets for our family Spring Break trip last month. It included admissions to Disneyland (3 day), Knotts, SeaWorld, SD Zoo or Animal Park, along with buy 1 get 1 free Amtrak. The price on Costco.com was much less than citypass.com. I am a Costco member so I did not pay the surcharge. One unadvertised benefit is that we could bypass the entrance lines. Cool! ^
