Upon check in, we were told we only were suppose to have 3 rooms instead of 5. We were booked for 5. We told the receptionist IHG reservations made an error. The receptionist did not listen to us, treated us as we were liars and provided us with a bill of over 1000 dollars extra to pay. After she finally decided to cancel the two rooms, she still tried to charge us for the amount of the five rooms. Note: She cancelled the rooms and tried to still charge us. We did the calculations on our phones at the desk for each room and she did her calculations several of times before LISTENING TO US and finally realizing she was charging us 1000 dollars extra. She admitted she did it incorrectly and in politely proceeded on with check in. She went and got her manager and the manager appeared and told us that at her courtesy she will cancel the rooms but we should be charged for the extra rooms that we did not book. She told us that three times as if we were at the mercy of “HER.” After figuring out the correct total of the rooms, we were asked for a 300.00 deposit fee, 25 dollars for each room, 3 rooms for 4 nights. We were not informed of this fee at reservations and we have stayed at several of IHG properties and never paid a deposit fee on the top of the room fee. We were told we would get our money back after we check out and that the fee must be paid. After all of that...After we checked in, We were given a room that was already occupied by another guest. My husband was the first to catch the elevator and go ahead and go to the room while I was finishing up with the receptionist. He made it up and He went into the room and the room was already occupied by another guest. We were given the room and key of occupied guest. My husband has an athletic physique and he is a black male and of course he could have been mistaken as he was trying to break into the room or could have been falsely accused of trying to do something to the guest...what I’m saying is it could have turned out ugly, my husband could have been tragically injured or killed but Thankfully, the guest was not in the room only their luggages and personal items were. My husband called and me and immediately left out of the room and went back to the receptionist and told me and her. The receptionist did not inform her manager of what had just happened, she blew it off, said they were sorry, there was a mix up and did nothing else but provided us with another room and key.
