When we did the EMM at TSL a few weeks ago the front desk told us that there would be no transportation available and we'd have to walk or take a lyft, but it turns out they were wrong. In the early morning before the boats start, they do have buses from the YC/BC to HS, even on days without an early event. One morning we were waiting for a bus to MK and between 6:15 and 6:40 two buses showed up for HS (yet none for the MK)! We did end up walking on our morning of EMM, and even at a super slow pace taking pictures, the walk took less than 20 minutes, so we didn't think it was that bad!
