Hello
I am new to Interrail and have never used it before so please bear with my lack of knowledge .
In a few months i would like to travel from Germany to London (using ICE then Eurostar) and then back from London through France to Offenburg (using Eurostar then TGV), now the second route is exceptionally expensive and last search showed a price of 300 Euros per person! And the whole journey to and back from London is somewhere around 500 Euros for one person
My question is: can one be sure that Interrail really covers such routes with expensive tickets without problems?
Thanks
