When I was there earlier in December, no issues for me. I did leave the room (near Casitas bus stop) 90 minutes prior to Park open (MK and HS). A bus arrived typically around 75 minutes prior to Park open. I would caution if you’re in GDT...the HS busses I was on first thing in the morning were full so we didn’t stop at GDT, went straight to HS. I don’t know if they send any directly to the GDT stop or if the next one also stops at Casitas first (every time I rode a bus, this was the case, whether morning or afternoon always went to Casitas first).
