If I recall correctly, it is possible to get stuck in King's Quest VI; there are items that you require to get out of the catacombs, and without them you're stuck once you're inside. I believe they obliquely warn you by kicking you out first and telling you to "prepare", but you can still come back without the items and they don't specifically list them, and at that point they'll happily throw you in without them. I found this out when playing this as a kid without knowing how to look up a guide. Fun times.
