Denni's family may think they're here to talk about persevering mothers and the importance of education, but that's not entirely true.
"The truth is, you represent every single mom out there who is breaking her back and sacrificing selflessly to make ends meet for herself and her family," Oprah says. "But my producers did tell you a little fib. Today's show is actually called 'Ultimate Wildest Dreams.'"
This one-night trip to Chicago was Denni's first family vacation...and it won't be the last! "We saw earlier that your dream is to someday go to Italy," Oprah says. "So United Airlines and Marriott Hotels & Resorts are sending you and your children on a luxury dream vacation to Italy!" Denni and her family will fly into Rome and then visit Florence.
Overwhelmed with joy, Denni expresses her gratitude. "I came here to thank you and to say how much I admire you for being the ultimate educator to all of us all these years," she says to Oprah. "You've been my inspiration."
