By far the most helpful for dh was Reflective Captioning - esp if you use Closed captioning at home -
Reflective captioning is available at many theater-type attractions at the WALT DISNEY WORLD Resort. This innovative technology utilizes an LED display to project desired captions onto an acrylic panel positioned in front of the Guest.
NOTE: NOT ALL PORTIONS OF AN ATTRACTION EXPERIENCE MAY BE CAPTIONED.
To utilize this system, Guests should contact a host/hostess at the attraction.

The one thing we learned is not all CM's are aware that this is in their theatre (they rotate CM's, some cm's are earning their ears!)
So always look behind the theatre for the red backward writing, and find a seat that you feel would be best to capture the words, and be comfortable - you get a "mirror" type device to place in front of you...
You wait in the que with the wheelchair guests, so you should be let in with them, in Animal Kingdom you cannot sit with those guests as it is UNDER a tree spot - some cm's arent aware of this -
at Epcot Honey I shrunk, its to the far side (near the exit) when I find it while the CM is locating the mirror, or someone who knows where the mirrors are - you should get your seat - one time a lady yelled at dh (we sat at the aisle, not the middle!!) I tried to explain, but she was miffed people "cheat" to get their seats... and of course we had to grin when she saw the device come over to dh... she sat there so embarrassed - and of course apologized...
I only offer that up because not many people realize this feature is available - but dh absolutely loved it - esp in MK Philharmagic - he loves understanding Donald Duck!!

Like Talking Hands stated, do mention to the CM's when you go by to get the glasses, or wait for the theatre to enter....
