The Alaska governor will spend two and a half days at Republican presidential nominee John McCain's home near Sedona, Ariz., preparing for Thursday's debate in St. Louis with Barack Obama's running mate, CNN reported Sunday. Plans had called for Palin to be in St. Louis for her debate preparation.

The aide who called Palin's debate preparation a debate camp told CNN the campaign decided to take the candidate to Arizona because it is an "invigorating and enjoyable place to prepare" for the vice presidential debate. The aide said it was McCain's idea.

Palin has been preparing for the past four days in Philadelphia.

Plans call for Palin to take a break from debate preparation Monday so she can attend a rally with McCain in Ohio, CNN said.
