The last two times that I vacationed at Disneyland, I took the Disneyland Express Bus from the John Wayne Airport to my hotel. I recently stayed at the Howard Johnson. Before that I stayed at the Candy Cane Inn. I believe that the bus stops at all the Good Neighbor Hotels, as well as the 3 Disneyland Resort Hotels. Check the above link. It should explain the bus process.
