I've traveled to Europe (as well as Asia) and over the years have found some ways to cut costs, especially for airfare and accommodations. I'm not guaranteeing I can save you money, but I've been able to save myself and many of my friends, hundreds of dollars per trip by using some of these tips.

What you provide: your budget, your desired location(s), your level of expected quality (i.e. sleeping on a park bench ;) vs Ritz-Carlton), also provide details on what you've already looked at (what flight costs you've found, what accommodations, etc)

What I can provide: I can look at what you've already found and see if I can find something similar for a cheaper price. At the very least you can get validation that you've found a great deal.
