Anyone played the PGA centenary at gleneagles

Hello,

        I was wondering if anyone has played the PGA at gleneagles and if so how long to allow for a round there? Going on a mini tour for my 30th and have been offered a good price on a 3pm tee time but being the end of september if it takes much more than 4/4 and a half hours I think we will struggle to finish. Have heard its a monster course with long walks between green and tee 

Thanks

Alan
