Inter-Railling

A good hostel is ~£40 person. That value that you found is per person @Yaniv Gerber per night 　 Anyhow, All in all - Hostels would cost ~£450. I've created a new route with price considerations assuming the other one we created was jumbled with places and too expensive to match budgets - here it is, if I recall correctly these are places we all wanted to go to: https://interrailplanner.com/plan/43546 - That consists of ~11 nights. Anyhow, a hostel/hotel as I described above requires a deposit of ~£155 for the 6 of us which is ~£25 per person. Assuming so, 25*11 = £275. Baring that figure in mind and the information that @Max Kraitt provided me with, an interrailing ticket can be booked whenever. Now, if we take flights in to conclusion from sky scanner, a flight to Amsterdam would cost £30 and a flight from Zagreb ~£80 - Implying flight costs will be approximately ~£107. Finally, if we take in to conclusion the costs and prices I've found then the conclusive so-called deposit that we'd have to pay as soon as possible will be ~£380. In regards to the ticket, the ticket can be payed seperately, or whenever one can afford to pay for the ticket since its not a rush. As long as accommodation and flights are booked then we're save. One final thing, in regards to the trains, we have to ensure to reserve seats. This costs ~€8 per train which can also be payed at a later date. In conclusion, if we were to secure payment for the essentials within the next 2 weeks I'd assume it would cost ~£380.
