that is why I ended my post with YMMVI would leave 9-14 for the Classic campaign. I have no interest in grafting that on to SotDQ in any significant manner. That's for the Classic campaign.
I used the Tarrasque as an example that DL16 might not be what he is expecting, not as something that cannot be overcome. I also would not use 1e at all, I would go with the 3.5 books, that is an improved and expanded version of the 1e/2e modules. Also, in my OP there were monster conversions for it alreadyYes, I would run Dargaard Keep as the SotDQ conclusion. I find removing encounters from a module that are a paragraph or less to be EASY. None of this 1st ed stuff translates to 5e without re-working it. That applies to every module or adventure ever published -- DL16 included.
The real reason for the OP to not use them is
which I was not aware ofI love the classic Dragonlance volumes, but I don't think that is what we are looking for.
The main problem is most of the players are thoroughly familiar with them and some of us have both played them and then DMed them for multiple different groups.
