Be prepared: this adventure takes a lot of prep work for DM's. Lots of different NPC's to keep track of roleplaying.
The dinosaur race was hands down the most fun part of this adventure; fun for both the DM and the players. The arena battle was very entertaining as well. I hope more AL adventures include more mechanics like these. There are several traps laid out for the players so make sure to keep track of those ahead of time. The players told me that they didn't feel very challenged during the combat encounters. We had 6 1st level PC's, but they were still an "average" level party according to the math, so I didn't adjust the encounters. If you ask the players before the adventure starts if they would like a "strong" playthrough, I believe 6 1st level characters can handle it. The grung battle was the most difficult; I dropped 2 players, but nobody died. The threat of the death curse made the PC's play smarter and coordinate tactics more than I've seen in other adventures.
This adventure was my very first one run as a DM and I recommend practice DM'ing on the smaller 2-hour adventures until you get the hang of roleplaying NPC's.
Overall a great intro to season 7.
