1 Month Eurotrip

So if the 5,000 is for two people, I would make that to 2,500 to get an accurate feasibility rating. That would be $70(ish) per day each which is less than 50 Euros. Very, very difficult. Especially because of the areas you are covering and a few expensive cities. If you still want to do it, expect to eat supermarket food, couchsurf some of the time and forgo many nights out.

What do you think is an appropriate budget for 2 people to be able to go on this trip? I can also reduce the trip length, but these are the countries I would like to go to.

You really can’t reduce the trip length by more than a day or two and still visit 6 countries. A reasonable pace is 5 days per country. Less in small countries than are close together, more in larger countries or countries where you want to visit several cities. Your itinerary is reasonable as it is.

I’d budget a minimum of $100 US per day plus a $200 emergency stash. This doesn’t include city to city transportation.
