First stayed here last year for one night on our way south and we vowed to return. We visited whilst the work was being carried out on the racecourse and yes there was disruption and a little confusion about the entrance but in fairness there was little the wardens could do about it. (They phoned me prior to our arrival to inform us of this.) We were also there at the time of the beer festival and didnt find it a problem. The facilities are governed by the racecourse apparently so again not easy to change but they were kept spotless. My only criticism would be the 10.30 closure of them, a little early for some. Overall would return,  Warwick is lovely!
