God. We ran through it with a full party. Problem was, all the players were GMs (I was the youngest of the group, and I'm 24) and the player was probably 13, and it didn't look like he had GMed very often.
And he had the attention span of, well, a 13 year old. He kept trying to sidetrak (his own game!) into conversations with the players.
Generally, he'd get lost in something (it's not a hard adventure to run, criminy!) and we'd pass time with conversations. He'd look up, and involve himself in the conversation... forcing us to try to remind him to get into the game.
It was... painful? But only because the GM bungled it. And he was definately only running it for the minis, I think - he got to keep the adventure.
However, I did like my character (I got the dwarven paladin, and it's nice being able to drop damage). Me and the Cleric (the woman at the table) did everything we could to help speed up the game, including taking initiative and whatnot (even though the GM insisted on using his own notes, which slowed down play, and didn't even accurately follow our initiative counts).
On the plus side, when I got home, my copy of Pathfinder #1 was waiting for me (there was shipping problem the first time). SCORE!
