got to AK bus stop at GDT around 7:10, 1st bus came around 7:25 could only take two parties (I know it was first bus because someone had been there since 6:45am). Driver said would call for another bus so I waited. About 20 mins later next bus showed and could only take 3 parties, luckily I was #3. On our way out I saw another bus pulling in so must have been the one they called for.
I waited today as it’s my second AK day so I’m more patient. (And rideshares were in demand and wouldn’t arrive for like 15 mins

). My conclusion is, as many others have said too and is sadly still accurate, if you’re staying GDT and want to be amongst the first in the parks rideshare/drive. Don’t bother trying your luck with buses you will probably lose.
