Is it possible to purchase a CIV return ticket from London International to Cambridge and back? It would connect with a Eurostar return ticket from Brussels-London-Brussels. If so, could it be purchased after arriving at London St Pancras/Kings Cross from Brussels? Everything I've read about this ticket is for those going the other way round, so I wasn't sure if it's available.
Ideally, I'd book a Eurostar + connection ticket via the UK version of the Eurostar website (the Belgian version doesn't offer this ticket). However, the website fails whenever I try adding a connection, often completely failing, and twice sending me an error message after the payment stage.
