I used this as a follow-up to another adventure, "A Most Potent Brew". My players had a blast, and described it as the most productive first session they ever had.

I just ran this adventure for a new group. One person was late, so I ran it with 2 players, reduced the number of enemies, and they had a blast. They ended up finishing in about an hour (probably because with only 2 players, there wasn't much in way of party discord), but I had a follow up planned, so that worked out nicely.

Fun little side quest. My players don't RP much, so got through it in less than 2 hours, but everyone had a blast with the odd creatures, and I had fun describing everything in the Feywild. Since there wasn't any loot listed, I gave each player a joke magical item that mysteriously appeared in their bags (gift bags from the Feywild!). I'm hanging onto this one if I ever get to DM another group.

I played with a group of 3 for seven and a half hours. They went completely off the rails after what was meant to be the final battle. My players wrangled a happy ending out of this.

I've never had so much fun. And they loved it.
