Hi, Lisa!
Oh, thanks for the compliment...I truly look forward to helping other guests plan their vacations. Congratulations on considering a cruise aboard Disney Cruise Line and spending a few days at Walt Disney World (WDW), too! (Click
here to see a video about planning a "Surf & Turf" adventure such as yours!)
Pricing for packages -- whether booked directly through Disney or through a third-party provider -- is going to vary greatly depending on the time of year, the itinerary, the ship, how far out you book and the stateroom category. Plus, there are other factors to consider once you're at WDW, too. If I were you, I would approach it from several different directions and get quotes separately and as a package from Disney as well as from other providers such as AAA or travel agents. With such a big investment, you definitely want to do your homework, get the best deal and make the right decisions for your family.
Thanks for visiting me on the Disney Moms Panel, and come back again if you have more questions. Have a wonderful day and a magical vacation. Bon voyage!
