Donate to support cancer research and you can party like a rock star here.

I’m proud to call Expedia one of my biggest clients (I contribute to their Expedia Viewfinder blog), and to celebrate Childhood Cancer Awareness Month, Expedia has joined forces with St. Jude Children’s Research Hospital in Memphis, giving everyone a chance to donate to a great cause and take a trip of a lifetime.

As part of this promotion, Expedia is giving away 150 trips, including 30 big “Dream Trips” each day for the month of September.

Giveaways last all month, and a new Dream Trip will be showcased each day. To support this effort, my colleagues at Expedia have rallied a bunch of expert family travelers across the country to feature their favorite Dream Trips Giveaways in the Well-Traveled Families for St. Jude Blog Carnival.

Expedia announced the program on the Expedia Viewfinder blog earlier this week. Then, my colleague, Anne Taylor Hartzell (a.k.a. the Hip Travel Mama), kicked things off yesterday with a post about a giveaway to the Fairmont Kea Lani resort in Maui, Hawaii. Today, I’m excited to feature a Dream Trip to Las Vegas, one of my favorite destinations on Earth.

The trip, titled “Experience Las Vegas Like a Rock Star,” revolves around a stay at Aria Resort & Casino. Here are the details:

• Round-trip air tickets for two (on Spirit Airlines)
• A three-night stay at Aria Resort & Casino
• A “Vegas Rock Star” club crawl (which enables you to skip the lines at popular clubs and travel the Strip in a party bus)
• Maverick “flight-seeing” helicopter adventure for two
• Two free tickets to Zarkana by Cirque du Soleil
• A limousine tour of Vegas highlights
• A $500 Visa gift card.

All told, the estimated value of this package is more than $3,000; it (or any of the other Dream Trips) can be yours for a suggested $5 minimum donation. DONATE NOW for an opportunity to win this trip (and see Expedia for official rules). And, hey, if you donate $25 or more, you can get a coupon for 20 percent off future hotel bookings on Expedia’s mobile app or 10 percent off purchases on Expedia.com.

To reiterate, ALL DONATIONS GO DIRECTLY TO ST. JUDE. That means all donations will help kids who have cancer. I can’t think of a better cause to support.
