By far my favourite module to DM in the trilogy (with no disrespect to the other two, this one is just really awesome in my book).

As a DM who really likes RP-ing, here are a few of my favourite things about the module:

1. This is probably the first time I've seen a module that presents the table with potentially conflicting objectives. Depending on which factions are presents on the table, there could be a situation where half of the table wants the wedding to succeed, and the other half trying to make it fall through. Plus, they might also have different objectives that they have to try to prioritise. Do you save the fireworks? Do you save the weapons? Would you go out of your way to protect the crew members? Furthermore, this also incentivise the players to RP amongst themselves, especially if they are aware of their conflicting goals. It is a very refreshing idea.
2. Yay for multiple RP-ing opportunities! You have the freedom to interact with any NPC in any point of the adventure, and how you interact with them will have its effect towards the ending of this adventure. The module also provides a lot of leads to draw the players' attention and want to speak to the NPCs. Quoting my table, "Guys, we're in a Nick Sparks movie!"
3. The combat encounters have a lot of callback to previous adventures, Wobbles from CCC-YLRA01-02, Walharrow II from DDEX1-9, the ghost ship to the whole S1 storyline. It's a great nod to previous lore events, and I happen to be a DM who DM-ed the whole Tyranny of Dragons series. Many of them also pose a good challenge, not in the traditional sense of swarming the players with powerful monsters, but creating situations that forces the players to split the party, even just momentarily.
4. Jay Africa played at my table. Yup, the author of this very module was playing at my table. Adding that to my CV right now. ("I don't remember writing in stuff that deals 19 damage!")

Nitpick: As an authentic Chinese, I, uh, wasn't particularly fond about the names of the Shou NPCs, especially the crew members. Or I'm just being too sensitive. Anyways.
