They charged me more and booked a wrong room

They charged me more and booked a wrong room. I just returned from a convention in Dallas that would have been a lot better if I had not used Expedia. I booked a room for 1 adult and 2 sixteen year-olds and requested two double beds.

I received confirmation for a standard room with 2 double beds. The rate was quoted at $148 per night plus applicable taxes and service fees - which is how my credit card was charged. When I checked into the hotel I was given a room with one king-sized bed. The hotel was full and there were no roll-aways available.

I immediately called Expedia and was told that the request for 2 beds was a "special request". I asked how they expected 3 people to sleep in one bed. After a lengthy discussion they offered to try to find another hotel. I explained that wouldn't do as we were attending a convention at the hotel. I also was told by the hotel that the room rate for the king was $122 per night. Expedia said they could not make an adjustment because their rate for a standard room was $148. They offered a $100 coupon for future use. I have not received any information about that - but I won't use them again!
