Booked a vacation package with Expedia for 5 people. Expedia charged me twice for the same airfaire, and when I arrived at the hotel to check in, the hotel informed me they did not have a reservation for me from Expedia. Spent half the first day of my vacation on the phone with Expedia. I ended up having to pay the hotel stay directly on the spot with the hotel. It was not the hotel's fault - they did not get a reservation from Expedia. The hotel has even sent emails stating there was no reservation for me. I am still fighting to get my refund from Expedia for a double charge for the same airfare and for a hotel reservation that I paid to Expedia but was not at the hotel upon check in. Expedia owes me over $4,000. So far, upon dealing with Expedia's Customer Service, they keep saying to give them 24 hours. It has been one month so far and no refund. My next step is suing in Court. Do not use Expedia.
