4 weeks? Took more like 4 years
Actually I never heard about the party bug until I was over lvl 90 (I don't hang out in Bomb Trade and shoot the breeze about bugs). So I guess I earned lvl 110 the good old fashioned stupid way; lords and solo maps. I even missed out on the bats, when they gave exp (gained about half a level). I guess I did gain about 10 levels from DoV, over the course of my 2 1/2 years, that was a fun thing to discover in the pre-alchemy days.
