We got through it three times, was a full group of 8 of us. The group make up was drk, war, mnk,4 smns and me on ast. We ate through that dungeon like you wouldn't believe. The tree clears were the exception, everyone in the group brought along three maps each, and we got the portal about 80% of the time.
Some notable drops we had: two copies of moonlight over thanalan, one copy of another song, dwarf rabbit minion, nutkin, 2 gaelikittens, a luminous fiber, glass fibers, and one person ended up with a full thavnarian set (from all of his maps lol).
Also, this only happened to us once, but the correct door lit up in room 5. (Only got one door lighting up once and that was it.)
