I am finally coming to do my research this year. I'm planning on going to Italy & hit quite a few places there, as that is really where my heart is. But, I also plan to go to Spain, Portugal, Greece & maybe Croatia. This could all change once I'm there, but I need to start somewhere.
Will I need anything else besides my American passport to come into EU in any area, & travel around to other areas? I know there's a 3 month limit to stay, if I'm not coming for a VISA yet. If I can come & travel around for 3 months with just my American passport, that will help me quite a bit! Do I need anything else to travel between other areas?
Thank you all for your knowledge & time. Greatly appreciated.
