We had the same thing happen to my husband except for the fact that they never caught it. We caught it at the airport when we were going through security. He just happened to notice that he had a boarding pass for Texas and we live in NC. The names were correct so we didn't look further than that when we got our boarding passes and turned over our luggage at the resort and apparently the other guy did not look either. Our case however, believe it or not, the same name checking out of the same resort on the same day. Needless to say, it was a pain in the tush trying to get the correct boarding pass and find his luggage. This was the only time I was ever happy that
MDE takes you to the airport 3 hours early. LOL The boarding pass was fixed but, there was not enough time for them to get his bags. His bags went to Texas and we got them 3 or 4 days later. Please check all of your info before your bags are out of your sight! Lesson learned here.
