Hoping some clever Mumsnetter can help please. We're heading to Wembley tonight and staying in Uxbridge, I know we've got until around 12.45 to get the tube but I was wondering if it's better to walk to Preston Road and avoid the slow moving queue, I can see on Google maps you can do so and avoid Wembley way (unless everyone is herded that way) it looks to be a 30 min walk ish but I can't see if it's on pavements etc I don't want to have to walk along a dual carriage way etc. any help would be greatly appreciated
