if i remember correctly, during the price increase fiasco, what we were told was "upgrades give you grandfathered pricing, while downgrading meant you forfeited it." that's why i made a pure reservation, while cancelling my GT reservation, with the intention of upgrading to touring at a later date. im sure in the future, there's gonna be the same upgrade deadline ultimatum (upgrade to GT before X date or else lose grandfathered pricing forever) for the touring.
