Complaint Review: Expedia

I wish I had read reviews before using Expedia.  I booked a hotel stay for my family at a resort through Expedia.  Just of out curiosity I decided to look at the hotel's website and saw a notice that said there was an extra $80 per night for children 12 and over. I contacted Expedia to determine if this fee was already covered in the price I had already paid.  After the rep looks at my reservation he says that I stated "under 12" and I should have stated "under 13" when i politely informed him that Expedia's drop down list has specific ages and I choose the age 12, he give me the number of the hotel and tells me that I have to contact them directly since I had already book. Really!!!

Had I not happened to look at the hotel's site I would have been hit with 100s of dollars work of extra charges and your response is that I should call the hotel when I booked through you??? At the very least Expedia should have given me all the booking information so that I could have made a more informed decision prior to booking. Now it is probably too late to book anywhere else. So disappointing.
