根据上面的提示, 非欧洲居民去北欧可以买两种pass：
1）Eurail Scandinavia Pass
http://www.eurail.com/eurail-passes/regional-pass/scandinavia
2nd class saver US$ 458
Save 15% each with a Saver Pass, when traveling with 2 or more people. ---->US$389.3 / euro 337

2）ScandinavianRail
http://www.scandinavianrail.com/railpasses/sweden/eurail-scandinavian-pass
2nd class saver $458

实际我们还有第三种:
3) Raileurope
http://www.raileurope.ca/rail-tickets-passes/eurail-scandinavia-pass/index.html
2nd class Euro $552 这个应该是美金吧?

我现在困惑的是, 第一和第三是不是一个公司阿? 第一和第二是一样价钱似乎, 这三种pass 有区别吗？？
请版主解答一下，谢谢。
