Yeah, the Ishras Ark levels are very lengthy but I don't actually hate it (unless you're after a 100% completion at least)
Look on the bright side, at least you get to blow it up after revisiting it
And when did this place become a boarding level thread all of a sudden?
I like all the board levels in the games except for one (looking at you, DCT)
Now the board levels on DTP were TERRIBLE.
I'm pretty sure that there are no board levels on DtP
