an escape wedding is what they used to call intimates. its a package with limo/cake/champers/flowers/ceremony and cake cutting. you can have up to 18 guests, you can also add bits like the coach/characters etc. but its basically a package.
a wishes wedding (aka custom) is one you design yourself. you choose everything, location/reception/food/music/decor etc. they have a minimum that you have to spend of $10k (goes up for certain days of the week). you have to meet certain food and beverage minimums too. this is more like a normal wedding, where you decide everything
a couture wedding is more expensive, its kinda like a package, david toutera (sp?) designed different "themed" weddings, and you can choose which one you want, its kinda like a template for a wedding if that makes sense!
hope that helps
