No, you generally cannot walk around with alcohol in the original Disneyland Park in California. For decades, the park was completely "dry," but today, alcohol is only served and must be consumed within specific table-service locations like Oga's Cantina, Blue Bayou, and the Carthay Circle (in the adjacent California Adventure). Unlike at EPCOT in Florida, where "drinking around the world" is a popular pastime, Disneyland maintains a more traditional family atmosphere where open containers are not permitted in the streets or queues. If you purchase a drink at a designated sit-down restaurant, you must finish it before exiting the venue. The only exception is the Downtown Disney District, where some locations allow you to carry drinks within specified zones, and the Disney California Adventure Park, which has more relaxed rules and several "outdoor" bars. Security is very strict regarding outside alcohol; attempting to bring your own into the park will result in its confiscation at the security checkpoints.
