I am glad the OP got her problem resolved.
BUT -- our experience with the reservation system, both on HAL and Princess, has been that it is essentially worthless. Unless you want to eat at 5:45 or 9:15, they always tell you it is booked up, even if you call the day before! We have given up even trying to make reservations.
However we very rarely have a problem walking up. We have never had to wait more than 10 minutes. Some people have reported half hour waits. I think most medical conditions would accommodate that much wait, especially considering that you are changing time zones anyhow.
