Coach USA/Gray Line of Anaheim launched The Disneyland Resort Express, a bus service that provides transportation between Los Angeles International Airport or John Wayne Airport and the Disneyland Resort in Anaheim.

The company purchased 12 vehicles that will be dedicated to providing frequent, on-time service, said Bryan O’Connell, Coach USA’s general manager.

The buses replace a previous service. The new vehicles are easily identifiable, with Disney logos and images of Mickey and Minnie Mouse.

The coaches operate every 30 minutes between LAX and the Disneyland Resort from 10 a.m. to 7 p.m., and they operate hourly from 6 a.m. to 10 a.m. and from 7 p.m. until midnight. The coaches run between John Wayne Airport and Disney hotels every 30 minutes from 10 a.m. to 8 p.m. and hourly from 8 a.m. to 10 a.m. and 8 p.m. to 11 p.m.

The service operates nonstop between the airports and the Disney hotels, then proceeds to other area hotels for pickup and drop-off. The one-way fee for LAX is $19 for adults and $16 children. For John Wayne Airport, the fee is $14 for adults and $12 for children.
