With the royal wedding of William and Kate a mere 24 hours away, it seems like everyone is getting in on the action -- TV stations, designers, shop keepers, pizza makers, and now ... Vegas.

Many online gambling sites such as PaddyPower.com and WilliamHill.com are offering Royal Wedding betting pools.

Here are some of the markets...

• Designer of Kate's wedding dress (Sarah Burton leads the way with 1/2 odds)
• Length of Kate's train
• Wedding Dress Color (which prompted us to ask just how different are Ivory [4/6 odds], Cream [6/1 odds], Pearl [6/1 odds], Vanilla [16/1 odds], Ecru [40/1 odds] and Egg Shell [40/1 odds])
• Length Of Sermon
• Wedding Reception Main Course

And Marketplace's favorite ... the Color of the Queen's Hat. Our bet is on green, despite yellow's lead of 11/10.
