Either:Any tips on the quickest route to Wimbledon from Ashford during the tournament?
At the end of a day's tennis, I would choose:SWT Wimbledon - Vauxhall, then LU Victoria Line to St Pancras, then SET St Pancras - Ashford Intl
SWT Wimbledon - Waterloo, then SET Waterloo East - Ashford Intl
Assuming you are travelling from Ashford Kent i would recommend HS1 to St Pancras, Victoria Line to Victoria, District line to Southfields where there is a special bus to the all England Club or approx 30 mins slower overall a "mainline" service to Charing Cross, walk the short distance to Embankment tube station (well signposted) and then district line to Southfieldsmassifmoss
Please note that the closest stations to the tennis are either Wimbledon Park or Southfields on the LU District line. (next two stns north of Wimbledon itself on the District line). I should check on Google etc as to where you need to go. Assuming you are only going for the day a travelcard should be fine if coming from Ashford Kent. Not sure about the Middlesex/Surrey one.
