I travel to Europe every summer for the last 12 years. I love Europe during September which is the cheapest month to travel coz the kids are back to school. If you want to travel FRUGALLY:
Accommodation: Stay in the hostel or www.airbnb.com (room for rent). It's better coz the host will tell you where to go
Dining: Just go to the supermarket and buy the sandwich, drinks and stuff. You can eat outside to taste the local food
Money: Make sure you don't exchange too much money coz some countries in Europe don't use Euro like Croatia, Hungary etc. I used my CITI bank atm card to withdraw money coz I don't get charge for any fee. For purchased, I also used my CHASE credit card coz there is no foreign transaction fee.
Countries for a month: My passion is world travel. I like the majestic castles, Most cities in Europe are rich in cultural history. Most cities promenade are surrounded by myriad of churches, palaces, museums, cultural landmarks & galleries. The castles from Medieval, Baroque to Mediterranean. It's truly breathtaking. Google the city of your destination.
These are my favorite cities: Dubrovnik, Croatia (My favorite).
Vienna, Austria. Prague, Czech Republic. Paris, France. Budapest, Hungry. Mykonos, Greece, Ibiza, Spain & London, England. Florence, Italy.
There are so many cities you can travel. Get a Euro train pass for a month. It's the best way to travel.
Let me know if you have any questions. You can email me and I will be very happy to help you. I traveled 3x a year. I just came back from Rio de Janeiro & Sao Paulo, Brazil for Carnival. Traveling is the best education you can give to yourself. You will meet people from all walks of life.
Enjoy & be safe,
