None of us here who have worked with Marie's materials remember her mentioning spinning a globe for the purpose of manifesting travel. I would suggest going back to the original source you heard it from.
From the perspective of Marie's course, I would suggest doing an activation card that is specific to your dreams of travel and putting it in your Success direction. If part of your reason for travel is also to connect with people overseas, you could also put it in your relationships direction. If an additional desire is to visit sacred sites and enhance your spiritual growth, you could put it in your Growth direction as well.
All the best!
