CANCUN, MEXICO—During their two-week winter holiday, Howard and Rosemary Gortenski of Arlington Heights, IL, have signed up for scuba lessons, even though both suspect that they will dislike the activity, the couple reported Tuesday. "Howard doesn't like to get his head wet, and I just don't see the point of getting all dressed up just to go under water for an hour," Gortenski said. "But vacations are for breaking out of the routine to experience what life has to offer, so I guess we have to try something new. It's this week or never." Gortenski said she'll make sure to secure some photos as proof of the couple's spontaneity.
