Our flight doesn't leave MCO until 6:30 p.m. We plan to visit Downtown Disney and the different resorts to check out Christmas decorations the day of departure. Which requires us to send our luggage to baggage check at the Poly while we wander around. So when we check in at the airport and they ask us if our bags have been out of our control since they've been packed we have to answer yes. How early should we arrive at MCO (as I'm assuming they'll probably check our luggage inside and out)?
