Dear Cardmembers,
Take advantage of this advance booking offer today to purchase a 4-night/4-day Magic Your Way Vacation Package that includes room and Theme Park tickets, and children age 3-9 can stay and get a 4-day Theme Park admission ticket, FREE. So hurry and book today! Your offer is available for stays most nights February 17–April 16, April 28–June 14, and August 14–October 1, 2011.
And when you stay at a Disney Resort Hotel, not only will you be in the middle of the magic, you'll also experience special magic, like:
Extra time in a Theme Park each day so you can enjoy more rides on select attractions with your family...and more Disney time together! (Valid Theme Park admission required.) Complimentary transportation to and from Orlando International Airport AND throughout Walt Disney World® Resort. It makes getting around as hassle free as can be! Fun for everyone whether you're splashing down Resort pool slides, watching movies under the stars or hitting the links with a complimentary golf club rental (at select Disney Golf Courses).
If you're not a Disney Rewards Visa cardholder, I highly recommend it for anyone who is able to use a credit card responsibly. Check out my previous DRV posts (under categories at the right) or drop me an email or comment if you'd like a referral code to receive bonus Disney Dream Dollars at signing.
