Buy a volcano for $10 million. Get 5 million XP. Sell the volcano and get back $5 million (half your purchase price back). So you are paying a net of $5 million to get 5 million XP. Same rates apply to Window of Reverie decoration and the Boulder Pile obstacle. It costs money but is a LOT faster than racing.
