My girlfriend and I are planning an Interrail trip to the UK this summer. We would like to take the Eurostar from Paris to London on 28 June. We have not yet bought an Interrail pass as we are still hoping for a discount. So we have not yet been able to book seats on the Eurostar.
Now we are not sure how long we can wait, i.e. how quickly do Eurostar seats usually sell out? I am happy to hear any tips and experiences :)
