Easy:
1. change resorts
2. change dining (near our resort is good)
3. visit different times of year- weather is always a huge factor! as is seasonal décor/seasonal activities at WDW (F&W, Flower Festival, appreciating the amazing WDW landscaping at different times of year. Will you see pansies, roses, or lantana? HM looks totally different when the grounds are covered in blood red roses vs. when they are aren't blooming. )
4. Visit parks beyond the Mouse. Harry Potter is amazing!
5. Visit Florida beyond the Orlando area! Take your pick! Drive west to Tampa, East to amazing St. Augustine/Cape Canaveral/East coast beaches, Drive south through Indian River to Ft. Lauderdale/Miami, or far south to the Everglades, or keep going north and spend a day in GA or SC! Florida is an amazingly diverse state! It has so much more than just WDW!
6. You can also change your trip - potentially by changing your mode of transportation- both within WDW and outside of WDW. Taking bus vs. boat, getting a rental car (eating a few meals offsite, staying offsite), drive vs. fly to WDW, fly to an airport other than MCO (Tampa!

)
7. Go with a different group of people.
8. Vary the duration/overall budget of your trip. A luxury short trip is very different from a long (or even short) budget trip. bot can be tons of fun.
9. Add or remove a half day in DTD, the water parks, Disneyquest, pool time, arcade time, visiting other resorts, esp walking around the Swan/BC lake.
