To find a good Disney World trip package, either use Disney's official website or use the MouseSavers website. The specific deals available for each site will vary by season.
Use Disney's Magic Your Way vacation by visiting the site and clicking on "Book Your Vacation Package." The site will automatically create vacation picks for a seven-day vacation beginning on the day you visit the site, though you can customize the date range. Initially, the site will offer results for all parks and resorts, although you can customize results by clicking on "Resort Location," "Resort Category," and "Resort Characteristics." The initial search results are based on Disney's picks, but you can click on "Sort By" to change the sorting by price or customize a price range by clicking on "Price Range." Clicking on an offer allows you to customize room selections within the resort and check availability for selected dates.
Use MouseSavers to view vacation packages for either the current or the subsequent year. The site provides links to a variety of vacation packages within Disney World's website and can be easier to navigate than the official site. Follow the links to view alternative Disney deals, such as Premium or Platinum packages. Alternately, you can read the value recommendations provided by the site to decide which deal is best for you.
