The shuttle is scheduled, and shared-destination (one goes to MK+EP, the other to AK+DS). They run about every half-hour or so, but take a mid-day break. If that works with your schedule, then you could try it. Personally, I think the $14 is worth it to be able to be entirely on my own schedule, and would use the shuttles mostly only if we had to split up, or all the adults were having BEvERages, but that's just me.
