Yes, I have.
Usually on the day I arrive in town as I typically don't want to use a admission for just a few hours in a Park.
So I would do a few other things in the area that did not require any admission.
Some of the things I enjoyed doing on property without entering the Parks were -
Riding the monorails around to all the connected Resorts, stopping at each one to enjoy the surroundings.
Grab a bite to eat, take a look around the grounds, peek in the shops, etc.
I used to do this at the Poly and Contemp a lot back in the day....not so much the Grand Flo.
Time it right, and you can watch the MK fireworks or The Electical Water Pagent from the beam.
Riding the monorail over to Epcot..just for the 'round trip' ride.
Scenic, exspecially once you enter the Park and get that great view from above it all.
Back in the days when Guests were still allowed to ride in the cockpit with the Monorail Pilot the entrance into Epcot was even more scenic - the view of Spaceship Earth as you approached from the beam was awesome!
Taking a cruise on the Seven Seas Lagoon via the ferry boat.
This is exspecially nice at sunset or early evening, or time it right and watch the fireworks from the water.
Walking around and exploring any of the Resort Hotels in the areas near the Parks.
All typically feature some unique things to see.
And lastly, there is always Disney Springs.
