Cheers Pete. I ended up booking at Southwark Apartments, seemed to be halfway between the Stadium and the pub, so was a perfect location for me.
Think you may have found the old AMI Stadium on Google Maps (Ex-"Lancaster Park"/ "Jade Stadium") in Philipstown/Woolston. Southwark Apartments are NOT halfway between the NEW AMI Stadium and the Cargo Bar (which are quite close together down Lincoln Road).
(From previous posts, I take it that the Cargo Bar 359 Lincoln Rd is the supporters' pub for the match?)
But no problem for you, because you're not too far from both stadium and pub:
Here is Southwark Apartments on Google Maps - to find the new AMI Stadium, just click at the top left and move left along Moorhouse Ave. till you get to the Park, then turn left down Lincoln Rd. clicking appropriately till you see the new AMI Stadium off Lincoln Rd (turn right down Whiteleigh Ave. & then left on Jack Hinton Drive). About 10 mins by taxi to the stadium for you - or if the weather's good and you want exercise, a thirty minute walk. There are also regular buses down Moorhouse Ave.
