to the family Rozza!!!
Well to get started you have already made a great move, by coming here and hang'n with peps who wanna make sure your trip goes off without a hitch.
First you have to pick where you wanna go:
Europe East or West
I have a feeling you already know where you wanna go...
You have to start your saving of $$$, and depending on where your going, will depend of what you will need to bring.
Western Europe is more expencive than Eastern Europe I would say a rough estimate of 500$ for everyweek your there, that is hostels, some sights, cheap food, and maybe one night of drinking. ( not including transport)
For everything you do the cost will go up.
is it possible to take any thing more than a backpack?
I am not sure if you mean can you use a suitcase to trek about, but if thats what you mean, then yes it is possible, but I would not recommend it. The last thing you want is to be dragging a wheeled suitcase through downtown Rome in the rain trying to find a place to stay. A suitcase is good if your taking a cab everywhere, know where you going to be staying EVERY night.
A pack is made to be easy to carry, comforatble, carry so pretty good weight, packs these days are pretty sweet, i use mine even when I could use a suitcase. Here is a sanario:
You just checked out of your hostel, you taking the train to Paris, but on the way you find a small town that you wanna stop and check out. A pack you just sling over you shoulder and go, a suitcase you would not be able to pull it off and enjoy yourself at the same time.
PLease, post as many questions as you like, there is always someone here to help ya!
