Did you have any luck in expedia honoring their best price guarantee? I made 2 reservations during the previous sale on expedia and then heard about a promo for 10% off. I could have (and should have) just cancelled and re-booked the hotels, but thought expedia.uk.co would honor their guarantee. First, I was denied because they said it only applied to reservations paid for upfront, not at the hotel. When I corrected them and showed that I did indeed pay the entire amount to expedia, they claimed I couldn't use a coupon or promo that wasn't available to the general public. I pointed out that since the promo was found on their home page, it certainly was available to the general public. I didn't hear a reply for 2 weeks and when I contacted them again, I just got " we understand your frustration, however, your refund is denied." No explanation. Guess that's how they roll. Doubt I will use them again, since it's clear you cannot trust them to keep their word.
