Worked well, you can use any train but depending on country you can have to pay a supplement for high speed trains, France, Spain and Italy being the worst. Eurostar is an £30 each way, France you are looking at 10 euro per TGV. It meant if you are going a short distance it's better to use local trains with no supplements. I didn't mind paying 10 euros for 6.5 hours for Paris to Barcelona as doing it not using the TGV would take ages. Also had a couple of travel days where I bought tickets rather than waste a days pass on a short journey.
When the cheap reservations run out, you can get on but pay more. I think in Northern and central Europe the reservations are less of an issue. I think it you want to travel on the fly it's not so great but it you are a bit organised, at least with your outbound and inbound leg then it works. For me being in the Midlands, just the travel to London being included in the pass made a big saving.
I think if you want to do one of the sleeper trains then you need to book further in advance as they seem very popular.
Saw this a couple o f days ago. How did your five-day pass work? Was it a pain to get booked onto the trains you wanted or fairly easy? Am I right in thinking it's only high-speed trains you can't use it with? Last time I went interrailing there was no Eurostar/channel tunnel, so have no idea how it works these days.
