Next Saturday (around 4pm), I'm needing to interchange between Waterloo and St Pancras with a very tight connection of 30 minutes. I've seen that most of the Northern Line's Charing Cross branch is shut, so I'll need to go a different route. Can anyone suggest which of the following is likely to be less busy/quicker: 1. Bakerloo line to Oxford Circus, then Victoria line to Kings Cross St Pancras 2. Jubilee line to London Bridge, then Northern line Bank branch to Kings Cross St Pancras 3. Bakerloo line to Piccadilly Circus, then Piccadilly line to Kings Cross St Pancras I've never interchanged at any of these three stations, so don't know which one would be better. Although number 2 looks a little longer, I'm hoping London Bridge will be less busy with shoppers. Any suggestions.
