After having owned the module since the days of 2nd Edition, I finally ran it and finished it up earlier this year, having run it as a mostly on-the-fly conversion to 3.5 (early on was easy, a bugbear is a bugbear, those 0-level bandits are 1st level warriors, their fighter leader probably has a masterwork sword. Later on required a bit more prep).
It was a pretty hack&slash campaign, started after the final Race and Complete books came out. 1 or 2 characters per person, with the group that finished it consisting of 4 players and 7 characters. It was a lot of fun, with some great encounters, some awesome combats, and lots of feats and options available to the players. It did really start to drag near the end, particulalry the nodes, but there was still some fun in those (fighting a few dragons, and being tossed around by air elementals).
The Prince- oh, that was a fun bit. The players seemed to just be missing the clues, or they had them and they interpretated wrong. They knew something was up, just not what. Finally, one of the players proposed beheading the vampire, and the others just nodded in agreement. The blood pouring out of the neck was a nice wake up call, but one Raise Dead later and everything was fine.
