I can help. Long before annual passes and Florida resident seasonal passes, I used to be assigned to Orlando for about a month every year. As an addict, I found a lot of ways to get a fix without paying.
Dowwntown Disney is one of them: lots of Disney music in the background; lots of cast member being magical; and you can see Epcot Fireworks from there at night.
Go to the Beach Club. Walk to the International Gateway and listen to the music of the countries and watch people walk between UK and France in Epcot's World Showcase.
Use Disney transportation. Go to the entrance of Magic Kingdom by monorail or boat. Hear the music. Time it for Move it Shake it Celebrate and hear differentmusic. Take a photo with the train station. Shoot, you can even see the AM park opening from outside the turnstiles.
Get on the monorail to Epcot. The monorail takes you inside the park, then outside. You can stand and hear the entrance music.
Take the bus to Animal Kingdom or Studios. You can see the park, you can hear entrance music, you can purchase souveniers.
Resort hop. You can go to all the hotels, no charge. Walk around, feel the fun. Eat the overpriced, yet good food. Wilderness Lodge: stand near the restaurant and hear the fun of people ordering ketchup or asking for butter.
Beach Club: Tell them you are going to Beaches and Cream. Walk to the beach. You can see a movie on the beach for free.
Boardwalk: Cruise the boardwalk.
The ultimate: Fort Wilderness: You can park and take a bus to the Pioneer Hall. Visit the horse barn. Walk around. Swim in the pool. Get a drink at Crockett's Tavern. Have a meal at Trail's End. Rent a boat and cruise the Seven Sea's Lagoon. Go to see Chip and Dale at the campfire movie.
Fireworks: Pick any MK resort, including Fort Wilderness and see the fireworks and have the music piped in. Go to the Hess station on Buena Vista, near Boardwalk and see and hear Illuminations. It also can be seen from the excess parking lot across from Boardwalk. You can also walk to the International Gateway and see and hear fireworks.
The list goes on.
