Language - Lots of people speak English and if you run across someone who doesn't know, then move to the next, lol.
Money - I downloaded a free app on Google Market called Flip Currency Converter, super easy to use. It has all current currencies. Also I used my credit card that has (No Foreign Transaction Fee) This is super important!!! You can charge anything with no fee!!!
Driving - I downloaded (Offline) Google Maps of each country! You don't need any internet for driving directions.
I noticed in each country something peculiar. It was different than the USA. Honestly the main take away from this trip was the immense gratitude for living in our beautiful country of USA. There is no place like this. We are not perfect but we care for one another. We are united despite our differences. We love one another and we care for people in general regardless of race and background. We have many cultures from all over the world, prospering and living their American Dream here. Perhaps that is the peculiar feeling I found; the feeling I felt was the lack of Dreams & love. They lacked the compassion and open mindedness, and weren't as welcoming to other cultures. We are all just people, trying to live the best we can, but I guess we all have our own ways of being. I did find some very sweet people which I was very grateful for. I was very impressed with Austria. It was very Clean, Organized, Prosperous, Wealthy, Beautiful, and Lush. There was no graffiti or crime. It was very strict and well governed. I hope that I can explore this country more later, I especially want to go visit Switzerland. That is another dream of mine :) In all I was soo happy when we came back home to USA. Oh goodness I just wanted to hug everyone and kiss every piece of the ground. It was an amazing feeling. I think that is the best take away from traveling; is that it leaves you with such a Tremendous amount of appreciation and love for what you have, that is the greatest gift to receive. We are blessed to be in America and Free!!!! Blessed to have many men and woman before us who loved this country and all its people and future generations in it, that they fought and died for our freedom! Thank you to all those who loved us so much to die for us. God bless the USA , God bless all of us :)
