Go for it!!! If you are flying on a 'participating airline' you can check your bags right at your resort and get your boarding passes at the same time. If you aren't flying one of those airlines, just leave your bags with the bell services folks. I am always packed up the night before. Hate packing on the day we have to leave. If we have an early pickup, either DME or a towncar, before noon, then we don't do a park. We just have a nice breakfast, usually a character meal and then hang at the resort. But, if we aren't leaving for the airport until 2ish, then it's off to a park for us!!! Plan on about an hour to get back to the resort...yes, sometimes that's too much time but better safe than sorry!!! Then you'll need about 20 minutes to retrieve your luggage and get it to the bus area.
