We'll be staying at Paradise Pier for only one night in October. We will arrive by rental car Monday afternoon, we will go to the parks for a full day on Tuesday and we'll leave when the parks close and spend the night near the airport to take an early flight next morning. DLR will close at 6 pm and DCA will close at 8 pm but WoC is at 8:15 pm, so I expect to leave the parks around 8:45 pm or so. Tuesday has MM at 7 am, so we will be in line around 6:30 am, so I'm not sure how you do this. Do you check out at 6 am and store your luggage or do you take it to your car? Or do you go the parks, return around 11 am to check out and store your luggage or take it to the car? Can we even store our luggage from 6 am to 9 pm? Since we'll have only one day I don't really like the idea of leaving the parks, but if it's the only way to do it, be it so. What has worked for you?
