With such an expansive property — we're talking 27,443 acres with 27 Disney hotels, four theme parks, two water parks, seven golf courses (including two miniature golf courses), one camping resort, a shopping district, and entertainment venue — it's a good thing Disney World has the whole transportation and travel part down. In addition to the Magical Express buses that run between the parks and the airport, the check-in service at the hotel was hands down the coolest feature.
On my last day at Disney's Port Orleans Resort (Riverside) I had a late afternoon flight and didn't want to carry my suitcase around me all day. That morning I was able to check in for my flight and check my bag at the resort, which meant I could spend the day however I wanted, walk straight to security at the airport, and not worry about my bag until I picked it up at baggage claim. Awesome.
