I visit London every few months staying at the victory service club , Seymour street, marble arch area as mam is ex service we get a 50% discount from the Q car park in park lane but its still £20 per night ie24 hours we are exempt from the congestion charge .. in and around Seymour street Westminster charge £4-90p for one hour if blue badge holder you also get 1 hour free the disabled bay is camera controlled and you can park for just 3 hours on sat 30th April I phoned Westminster council to pay for the 1 hour them 1 hour free during my chat the computer was not working .. I explained who we were and was booking the car parking ... the operator asked me to call back in 10 minutes she then said her supervisor had given her permission for our car to park wherever we wanted to over the next few days till Tuesday night FREE OF CHARGE ..this enabled the two of us to use our own car and save cash as we did not need taxis ...happy days ...
