Booked tickets via Eurostar Domestic Sales from Cambridge [CBG] to Lndon Estar CIV [LOE] the other day. The lady at the call centre was very helpful. You pay buy credit/debit card and can pick them up at your local station as long as it has an enabled TVM. No problems.
I have checked the fares to LNDON ESTAR CIV [LOE] and there doesn't seem to be any single/return fares just travelcards? There does, however, seem to be fares to LONDON INTERNATIONAL CIV+ [LNE] priced at £13.55 for a EOS and £17.80 for a EVR with DSB railcard discount applied.
Sorry to highjack thread but as it is of a related query:-
I have recently picked up the tickets from CBG to LOE and have noted that the routing states any permitted without the "+" indicator to allow connecting travel by London Underground. Now, I may be wrong though, I thought that Cambrige to London was valid by two routes 1) via Royston & the ECM to London Kings Cross [KGX] and 2) via Bishops Stortford to London Liverpool Street [LST]. Although academic, as my friend will be travelling direct to KGX for the easy transfer to London St. Pancras International [STP], if 2) is a valid route why no "+" to allow tube travel from LST to STP?
