It may be every girl's dream: a big, fabulous wedding.

This week a group of vendors is auctioning one off, complete with couture wedding gown, to honor another girl's dream: to cure cancer with lemonade.

Alexandra Scott, the Wynnewood 8-year-old who died of cancer in 2004, raised more than $1 million to find a cure for childhood cancers. She started by selling lemonade in her front yard.

To date, the Alex's Lemonade Stand Foundation has raised more than $19 million and funded more than 80 pediatric cancer research projects nationwide.

The Omni Hotel at Independence Park is donating a wedding package worth more than $50,000 to aid Alex's cause.

"I have two little girls, so Alex's story so resonated with me," said A.J. Williams, the Omni's general manager. "We figured, 'What is it that we do well that we could give?' A wedding."

The package includes a rehearsal dinner at Panorama Italian restaurant, a wedding ceremony and reception at the Omni's Azalea restaurant, a couture wedding dress, rented tuxedos, bridesmaids' gowns, hair and makeup, a DJ, photography and videography services, wedding rings from Barksy Diamonds, a custom-designed wedding cake, a penthouse suite on the wedding night, which is July 18, 2009, and an all-inclusive resort honeymoon in Mexico.

The auction, A Wedding For Alex, takes place on eBay.

The bidding starts at $20,000 and ends Friday.

The wedding will be awarded to the highest bidder, and proceeds of the auction will be donated to Alex's Lemonade Stand.

"Alex touched so many people," said her father, Jay Scott. "To help fight childhood cancer, it would make the wedding that much more meaningful."
