Alex and Katie were staying at a resort in Cancun, Mexico with the Duffey family. They just finished eating at a fancy restaurant when it finally stopped raining. Pauline asked, "What should we do next?" Katie suggested getting their pictures taken by the Cancun sign on the beach. Alex and Katie posed by the sign to get their picture taken. Then, Alex got down on one knee and asked Katie to marry him. After about 45 seconds of Katie asking, "Are you serious?! Are you serious?!" She finally said yes! The next day, which was also their last day in Mexico, they unfortunately had food poisoning. But, Katie would do it all over again, even if it involved getting food poisoning once more.
