HOP ON HOP OFF

If you go to the multiple country and multiple city. I suggest you using the train. It's much more save than using low fare plane. Depend on the frequent and your destinations.

Check this website:
www.eurail.com

You can choose how many days and how many country you visit.
"Days means days of you using the train. One day you can take many train"

ATTENTION:
1. This is just Europass ticket. Not Include reservation
2. Take 2nd class. Cheaper
3. If you take the train that need reservation. You have to pay reservation. If you pay Europass for 1st class, you can book reservation for 2nd class.
4. If you don't want to book reservation. Find regular train! You can just hop on and bring your Europass.
5. Reservation fee: 3-20 Euro variatif.
6. Always chek the web. They usually give the special offers. Our last trip, we got 1 free day train trip.

Not all the train station got elevator available used except for disabled. So think again about the luggage.

Train in Europe is comfortable. There is space for luggage, electricity for you device. And sometimes the information destination in local language. Pay attention.

If there is something happening. like suddenly stop for enough long time. Ask your surround. The train may be broken and you have to move to another train.
"Don't ask, You missed the train"
