Everyone that wins a Regional has a spot in the Worlds event reserved for them already. No planning needed.
There are two possibilities here, either you bought your ticket to worlds event with the travel and hotel costs included and the knowledge that you would win your regional, highly unlikely for anyone even for two time world champion pheaver. Or you win a regional and now have to purchase travel tickets/hotel rooms which the best ones already reserved for.
I am not saying the reserved ticket for worlds is a curse, it just seems a bit weird to me.
