So, reading the Light Novel and Manga is kinda funny, given the manga appears to have changed this arc quite a bit. Like, the overall trajectory is the same, but how they got there is different… also seems like the mangaka really wanted to include the 4th duke house and his ace (which in the LN only really gets mentioned or shows up in side-stories up to this point.
Personally, I found the "guys, there's a boat falling out of the sky" a hundred times funnier in the Light Novel.
