I haven't heard anything about that as of yet. To the best of my knowledge, you pay any checked baggage fees when you checkin at your departure airport, for that particular leg. When you get to WDW, if you have fees to pay for your return, you just call the BAGS number (on your DME departure notice), pay the fee with a credit card and then checkout the next day. Then you can use the resort checkout service. Your number of bags could very well change...I know that happens to me all the time. Those nasty last minute things I just 'have' to buy...that means I have to get another bag to carry them home in!!!
