I found the staff to be remarkably helpful and accomodating once at the door. I would suggest arrive early, explain your situation, ask for help. Im sure you'll have a lovely evening.
The paid parking next door, as mentioned, has a steep slope access. I would recommend dropping your wife off first before parking. Also, depending on the time you arrive, there is local street parking. The venue issues seating on the evening. We try to arrive when the doors open, get our seat allocation then go and have something to eat. Returning in time for the show. I hope this helps.
Im also ADA but didn't ask about ada seats but the ailes are fairly easy to get through . Its older theater. There is parking paid to the right of entrance but it very limited i suggest getting there way early parkingis a problem
There is paid parking next door. There are very few steps at all in Largo, so getting to the theatre shouldnt be an issue but im not sure about seating.
