Disney wedding packages widely vary in price depending on if you're doing a low-key, intimate wedding or an extravagant, go-for-broke event. Packages are completely customizable, so you have to decide what you want to splurge or save on.
To give you an idea of base prices, Disneyland weddings start at $6,500 for up to 20 guests (including couple) and $15,000 for up to 1,000 guests. Disney World weddings start at $3,500 for four guests plus couple, $7,000 for up to 18 guests plus couple, and $12,000 for more than 18 guests plus couple.
Keep in mind, though, that even the most basic package is a "one-stop-shop" that includes wedding planning, florals, discounted rooms, and discounted theme park tickets, so that's something to consider if you have sticker shock!
