I got a bus from OKW to AK almost 2 hours before opening on a day that wasn't EMH. But there was bus service meant for the people who had ADRs for the character breakfast. I had the Backstage Safari tour scheduled, and was very relieved to be able to get a bus there for my tour. Since I was the last bus stop at OKW, the bus made no other stops, and I arrived at AK 1 1/2 hours before opening.
