Interrail.eu offers special discount, 15% off on every Interrail pass you purchase during the March of 2018. Buy now and travel in summer.
Interrail.eu offered this spring promo last year as well and it was very successful – as you can already start planning your summer holiday in advance.
It also makes sense to book Airbnb, hostels or hotels in advance as well to get the best prices. Connect that with an early purchase of your Interrail pass and you are free to start planning your summer.
At rail.cc we offer a lot of helpful information: the big Interrail forum with personal help. A list of all Interrail night trains. The trains you can use with Interrail and possible reservation fees. And of course a guide for first time Interrailers.
