My experience today - arrived at HS and was at a kiosk at 9:10 (surprisingly no line at the main one right at the junction where you turn to go to ToT/RnRC but still on Main St. (I know it has a different name!). Also, all day no lines at the kiosks by TSMM which also surprised me. ToT kiosks were always packed when I was near there.
At 9:10, searching for a party of 4, I found:
-No TSMM at all (not surprisingly)
-RnRC only available after 6:40pm
-GMR available all day, including immediately (9:10-10:10 window). Normal but people yesterday saying GMC wasn't available at all. We grabbed it for 10:45 to fit in our plans.
-No ToT at all
-Star Tours available only in the evening (I think around 7:10, which surprised me)
Everything else I noticed was available as far as I could tell (know Fantasmic was - didn't look carefully at the remaining Tier 2's but know I got LMA & Little Mermaid just when I let it fill in).
