My dh and ds are hard of hearing, and I second the
Reflective Captioning You will need to get the routine down for some places, but dh LOVED it! When you go to the parks, you get a map, and their are symbols that help remind you what exhibit uses what device. For Reflective captioning I remember the Hall of Presidents - always look at the back of the theatre, you'll see a box thingy with red lights, backwards... Now for the popular 3D movies, when you check in, tell the CM you need reflective captioning, if they dont understand, say you'll wait with the wheelchair... and then when that cm comes out, mention you need xx amount of seats and one mirror for reflective captioning... if that cm doesnt understand, ask him to find out where the mirrors are stored... for Honey I shrunk the Audience the best seat is to the far left back, now we went in got our 3 seats while the CM went searching for the mirror, and the rest of the audience came thru... (this was the only place where we were questioned by people why we "cheated", once they saw the mirror, they felt guilty!! Usually you get the mirror before the audience comes in!!)
In Philharmagic in MK you want to the right end, we sat kinda in the middle front... (we went after midnight it wasnt full then!!)
Now for Its Tough To Be A Bug, it took the CM's awhile to find it, so we sat thru the first show w/o the mirror, and then they let us stay for the next show since they found the mirror, and we were set up... DH was surprised at how much he missed without the Captioning!!
In MGM we rented both devices, we did find them to be heavy, the hand held captioning wasnt (last summer) set for the new "Backlot Tour" we got a kick out of reading something entirely different than what we were seeing... he did like it in the Walt One Man's Dream exhibit if I remember correctly... The FM device was ok...
I carried the devices in a Tote Bag, and just handed them to dh when we got situated... He is very embarrassed that he doesnt "hear" and needs aides... but the Reflective Captioning was the BEST!!
