My husband and I took the family on a trip to Virginia Beach one year.  We planned this great two week vacation wherein we were spending 10 days in Virginia Beach, then going to Washington, D.C. for a couple of days and stopping at Hershey, Pennsylvania on the way home.  Before we left, we made sure we had gone to maquest and made sure we had all the directions we would need.  Not once during all that driving did we get lost or find that our directions were faulty.  Not once did we feel that we should have purchased a map instead.
