I posted this earlier in the following thread. Also just tested another solution. You can go with 4 as long as one of the toons doesnt play the golf part of the game and just stands there. The toons I was with had no clue what I was doing. We have survived 3 rounds of the golf. I stand in the tunnel and wait. I dont go on the grey or green in that part. We finnished all four of us.

EDIT: I went in with Duck a la ronge, Oinka de Vida and Tymora because they went in 3 times and came out immediately 3 times. One of them asked me to go with them. I wanted a group of 3. But went in because I didnt know how to say that in speedchat. I didnt want to get booted again so I decided to try the not playing that round technique and it worked.
