We are still going. Our flights were cancelled about a week and a half ago, but I was actually happy. The flight was the part that made me the most nervous. We can control (to a certain degree) our park / hotel experience by just leaving the area if we feel uncomfortable. They tend to frown on that on a plane in flight

.
So, we're going to drive down from PA. We managed to snag 3 nights at Hilton Head Villas before our Copper Creek reservation and then booked 3 nights in Charleston on the way back. We've decided to just make an adventure out of it as we've never been to HH or Charleston before. I also think having the car at WDW makes me feel better about the trip overall. If we decide Disney transportation isn't a good idea for us, we have the option to go our own way.
