Travel budget in Europe for 3 weeks

Hi, I know that this has been tackled before, but I just would like to get some opinions if 3,000 Euros budget for a European trip for 25 days is enough? Scenario is as follows:

1. Traveling to: Italy (Rome, Bologna, Venice, Milan (1day)); Amsterdam, Prague, Rome is my last stop again before flying back home

2. I have paid for most of my plane tickets train tickets (Except for the metro rail) accommodation: accommodation balance I need to pay is max 500 euros

3. I have not paid for museum passes I plan to buy (Amsterdam), as well as daily metro passes

Looking forward to feedback, thanks.

You've already paid for lodging everywhere ?

'Scuse me, but you're closing the gate after the horse is gone.You should have asked b4 you paid for anything.

We might have saved you a hundred or two, on your flight from home. Thats your biggest expense.

If you pay for beds b4 even leaving home, that kills sponteneity.
We don't know about any place till we're there.

I paid three days up front for a pensión in Cuenca.
To learn later, it could be seen in a day. No try, no gain. Its all a learning curve. And our biggest percieved road problems, become our favorite stories.

Even if we get robbed, the best medicine is just saying,"What was the lesson in this?"

And shrug it off. Learning to laugh at ourselves. Hey. Marco Polo was really looking for AUSTIN, Texas!

All guide books say money belt. My Rick Steves six dollar wonder has saved assets and passport three times that I know of. Its ten years old and washable.

Straight answer is, you three thou should last you about two.5 months.
I'm 72. I only stay in hostels any more. For the foreigners I learn from.

And I never book ahead. I may learn something else and wanna change route.

Have faith. Trust God, but watch your stuff.
Cops can't do a thing for us.

Use your noggin b4 using credit card. Ask old timers FIRST.

Why only three weeks? Money?
I hope you didn't put deposits on your rooms.

check it out b4 you rule it out.

Talk mostly with foreigners. Otherwise your trip is just abc. Another bloody cathedral.

Why not go home a little wiser than when you left?

Well, you don't say enough for what? If flights and hotels/hostels are already paid for what are you planning to spend your 3000 on? Meals, museums, what else? At 143E per day you have enough to pay for a lot of stuff. Certainly more than just meals and museums unless you are planning on eating at Michelin starred restaurants.

A basic backpacker budget for Europe is generally considered to be 50E per day. That hostel, supermarket food and the odd beer or museum entry. It does not include transportation.

A typical 3 star hotel tourist on the other hand might well spend 200E a day for the same.

Which are you? You leave out more info than you provide.
