Welcome. There is only one Garden Wing as the other was removed to build BLT. The Standard View rooms are closest to the Tower, however, none of the GW rooms are very far from the Tower. There is a covered walkway from the GW to the Tower.
Welcome. A great place to start your research on CR is the first two pages of the thread. WDW seems to be very conscious of ADA requirements, so I'm certain your DH will be fully accommodated. There are CMs available throughout CR and CC as well as Braille menus and other services I'm not familiar with. There is a DISabilities forum here on the DIS that might also be helpful to you.
You can make any requests you'd like, however, requests can never be guaranteed. The Standard View rooms are closest to the tower, but no GW room is very far from the Tower. The furthest GW room is less than a 5 minute walk to the entrance of the Tower.
The decorations might be up by the end of your visit. The WL tree went up on 11/19 last year so they might not be up yet before you leave.
Have you called or emailed Disney directly to ask specifically about accommodations for the blind? They would be able to give you a very specific answer.
WL guests affected by the pool closure will have transportation available and use of the CR and FW pools. So you could keep your reservation, do all the things your family is looking forward to
and use the CR pool.
Welcome! The Garden Wing has Standard View rooms that overlook the parking lot and monorail. A Standard View booking in the Tower is actually a Tower Bay Lake View. You can always add an applicable discount later to a reservation, so it doesn't hurt to book early. Disney also has very gracious cancelation/change policies if you change your mind later.
Welcome and congratulations! I'll add your dates to the Log-orail. Don't give up on trying to get a Tower room as people cancel all the time. Also, in the GW are fantastic Deluxe rooms that would be perfect for you and DH. Were any available?
I hope you have a wonderful Disneymoon
