Did this last week. We waited by Cosmic Rays until rope drop. Were walked over to Space. We merged with the rope drop crowd under the People Mover, with the EMM crowd slightly in front. Other folks from the rope drop crowd tried to push up front (we actually had someone say, ‘just use some elbows and push’ - it’s the thing my DS remembers the most!) but when we hit the merge at the entrance we were about 20 people back. And I am a VERY slow walker, 5 feet tall with not much pushing power
We finished Space and did Buzz before heading to breakfast. Got there around 9:30ish.
