I'd second the idea to avoid the EMH park.
Bring along some favorite music, even Disney music for the car drives or while getting dressed in the mornings.
If you like good coffee, get some for your villa, and have a travel mug for the short drive to the parks. It's so much nicer for coffee drinkers than the nasty black water (pun intended, for you campers

) masquerading at Disney as coffee.
Have a soft cooler to stow in the car with cool beverages and/or snacks. Very nice when you're park-hopping or driving back to the villa for a pool swim or nap or at the end of a busy day - especially handy if you'll have kids with you!
Keep an extra pillow from the room in the car, if you'll have little ones with you. So much nicer at the end of the day than holding a wiped-out tyke on your lap on a Disney bus!!!
Add whatever Disney touches you'd like for the villa - stuffed animals, Mickey toiletries, maybe buy Mickey ice cream bars at the grocery to have by the pool.
Go into this as an adventure, something new and different. Look for the benefits of staying offsite (better food at better prices in offsite restaurants, space to spread out, multiple bathrooms & TVs, etc.) and don't compare everything to your favorite onsite things. Let it stand on its own merit. Enjoy!!!
