Disclaimer: In no way am I criticizing you as a DM or your group. But regarding prep:I knew that this was a sandbox campaign, and I wanted to be well prepared. In addition to purchasing the module on Roll20 (since we play online), I also purchased the hardcover adventure for reading away from the computer, read numerous guides, watched videos on YouTube, and downloaded a DMs Guide on DriveThru. The DMs guide ended up being very helpful as it provided additional encounter maps that aren’t included in the hardcover (or on Roll20).
Using the various resources, I followed the advice for presenting the best starting quest and Ten Towns quests from the beginning.
It sounds like all you did was let others tell you what to do. Basically, all input with no output. In my personal experience, it is the DMs with either: A) a high rate of output or B) a high depth of output, that manage to make AP incredible. It has been the same when I DM as well.
I know, an AP is supposed to be buy and play, basically the equivalent of plug and play. And again, in my experience, they are. But to make it better than average, you have to have output, not input, prior to play.
