I know with Flight of Passage you miss the entire lab portion of the queue, but you also miss the lab when you rope drop it in the morning. I have actually never seen the lab because I always rope drop it. Peter Pan you skip the entire Darling nursery but it's not worth standing in a 100+ minute line for, like at all lol. With Haunted Mansion and Pooh you skip the interactive stuff outside and same with Mine Train but on my last trip I didn't see the interactive elements turned on so maybe they're not running them yet.
Unsure if you skip the preshow with Hondo for Smuggler's but when I rope dropped it I skipped the preshow entirely.
