After much searching I too have found the "we are not sending them out" message .... I can see a deep and meaningful discussion being held with the ticket man on the underground . . .
I can't see that they can argue if we a) have an Olympic event ticket, and b) have a rail ticket from our start point (Bicester North) to Stratford International station ..... but have no means of getting the Travelcard.
What's annoying is that we planned to have a tootle round in London from about mid-morning before going to the Olympic park at about 1800 for the evening performance.
BTW - the travel routing is interesting ... our return trip : Stratford (the E15 one, not the real one wher I live) to Marylebone is "overground to Liverpool St; Met line to Edgware Road and walk (back?) to Marylebone" ... surely Baker St on the Met line makes more sense ... or better : Central Line to Oxford Circus, Bakerloo to Marylebone.
I appreciate that there's the opportunity to play Mornington Crescent here ... but like many I can probably negotiate any part of the underground network without the aid of a map. WTF are the people that wrote the instructions thinking about?
