This worked really well for us. It was less expensive than the Dulles long-term parking and pretty seamless once you get the hang of it. We did luck out on the return trip, as the shuttle was already there when we dragged ourselves to the pickup location. If we had missed it, I�m assuming the wait would have been almost an hour. It was late evening and we were exhausted from our trip and having to deal with the awful behemoth that is the Paris airport. I can�t imagine having to sit in the heat and wait another hour, but, as I said, we lucked out. Everyone at the Regency Hyatt was professional and helpful. Recommend this alternative! We paid about $110 for 18 days.
