Fist and main complaint...check in is HORRENDOUS! This was our third stay and the third time our room was NOT ready by 4pm...this is peoples first impression and its not a good one. We stayed in the waterfront tower, nice room, quiet and clean. Very low water pressure and the water wasnt very hot. Disappointed the buffet is not open for breakfast. If checkin could be fixed, i would give 5 stars but that is a definite turn off....fix it harrahs!
