Second, we have designed these vacation package tours the way Americans like to travel. We have picked hotels that give you the flavor of Europe while providing real value for your money.
We Americans have always like making up our own minds. We have tours by escorted (护卫)motor coach or your own rental car. And land packages in Paris that start as low as $ 299—$1289.
