No, you're pretty much right. Except that if a DTD bus comes first- you could go ahead and take a DTD bus and go from there to ASMu. I reckon if an AK bus came by that would probably be the fastest- assuming AKL is closer to AK than DTD and thus getting that bus, going to AK, then taking a bus from there to ASMu would be the shortest route by bus?
(to op- in other words by bus is your only way unless you use your own vehicle or taxi)
