I received an email from Disney Destinations last week, and one of the offers listed is 30% off a Deluxe resort either the Poly or Animal Kingdom Lodge... with a "Savings on stays most nights April 28 to June 14, 2011 and August 14 to October 1, 2011 when you book by March 27, 2011." We actually want to book something for October, but my question is, can we book the current special for end of Sept. and cancel no strings attached and rebook in October if something better comes along?
