Amen, Kristy. If you're responsible for getting a group to a destination, you've got to name the destination, provide enough details to get there, and share any parameters (like budget for the trip, arrival date, acceptable modes of transportation, etc.). If you just say, "We're taking a trip in the continental U.S." and send people on their way, folks will go off in a variety of directions and spend random amounts of time and money getting "there."

Establishing clear goals and expectations seems like a no-brainer. It's amazing to me how many managers fail to do this.
