Forget Thanksgiving and Christmas; this holiday season is all about the Team Cupcake wedding! Ashley Hebert and JP Rosenbaum are getting hitched on December 1, 2012, and this weekend, Ashley and JP and their BFFs have flown South for a weekend of partying it up in Arizona. Of course, the festivities are also being filmed for their ABC wedding special, which airs December 16, 2012.

A local tipster spotted Ash and JP the gang checking into the posh W Hotel in Scottsdale. “It’s very sceney, the perfect place for a blow-out bachelorette party,” our sleuth tells us. The hotel features the hip Sushi Roku restaurant and a Bliss spa (perfect for recovering from a night of sake bombs). Our only question: Did Boo get to come too? According to the W Scottsdale website, pets are welcome!

Bachelorette Season 8 alums Arie Luyendyk, Jr. and Jef Holm are also in Scottsdale this weekend — and accidentally ran into Ash and JP's film crew! On Saturday afternoon, Arie tweeted: "Awkward moment when we ran into Bachelor production here at the W in Scottsdale. IFB and walkies alerted my spidey sense. #QuickJefLetsBounce."
