I'm definitely interested in a trip around Europe. Gonna have to do some serious number crunching between now and then though, this trip alone is looking to set me back about $2,000 USD
Hmmm... yeah at least. To give you an idea, my trip to Genesis 1 costed me about $2150, and Genesis 2 was $2700 (I booked pretty late, and the flight alone was more than $2000).
For this, I flew from Paris to the west coast, and spent 2 weeks there, travelling a lot (1st trip : Paris > LA > Anaheim > San Diego > Antioch > San Francisco > Vegas > Paris, 2nd trip : Paris > LA > Camarillo > San Francisco > Antioch > San Francisco > San Diego > Paris).
I didn't plan those trips that well, so I could have found much cheaper prices to travel whithin the US, but you get the idea. The only good thing is that I almost never went to the hotel, except during Genesis.
Life is more expensive over here (especially in Norway), but compared to my trip, you have the advantage of leaving from the west coast. And if you plan it early enough, your trips between European countries won't cost much.
It also depends of the countries you wanna visit, and overall, what you want to do.
I may make a thread in the Europe boards to gather answer all the questions of those who'd want to do that.
