Millennials may still largely be struggling to buy homes, but they're willing to shell out big money to see friends and family get married. New data from TD Ameritrade's 2018 Millennials & Money survey found that 53 percent of millennials say it would be "worth it" to go into credit card debt if it meant they could attend the wedding of a close friend or family member.

More than a quarter of survey respondents say it would be "definitely worth it," while another 27 percent call it "somewhat worth it."
