Not long. It's more a matter of how you drive it during the break in period. If I had a trip planned, getting any new vehicle would no slow me down. I once picked up a brand new car, took it home, packed it up, filled it up w gas and went on a 2800 miles. I sold that car w 224k miles on it and the oil still did not move on the dip stick between oil changes. The nice thing about a trip is that the break in is over before you know it.

Just follow the break in driving instructions and you will be fine.

Took mine from 1600 to 2900 miles on a mountain trip to New Mexico a few weeks ago. With all the wind and craziness on the road it seemed like the perfect break-in drive. Did my 3000 mile oil change today in fact.

To me the only thing to worry about on going on a long road trip with a brand-new car is that you want to avoid driving at just one speed (really one rpm) all of the time. And this is just for the first 1000 miles. So I'd just avoid using the cruise control for the first 1k, and perhaps try to make a conscious point of driving at different speeds from time to time. This can be a bit of a pain on the interstate, but still can be done. (Or you could take state routes, which take more time, but can be more interesting....)
