We did it. Found cheap airfare from PHL, early morning flight. Lyft to EPCOT, spent all day in the park, lyft back to MCO in time for our flight home. Total cost was $250 for 2 round trip airfare, and $70 for both trips with lyft. Snacks in my backpack, quick serve and kiosk snacks for 2 meals, and got the whole trip soup to nuts for under $500. The only con to the whole trip is you are going full tilt from early morning till midnight. Fun but exhausting. Will I do it again? Even though we go 4-5 times a year with short trips, ABSOLUTLY YES.
