We were in the BMI lounge, in March. Since you have a person in a wheelchair I would recommend the BMI lounge as it is close to the gate. The lounge is nothing spectacular as the other OP's have said but I found it quiet and good for relaxation. There were some snacks and drinks. They were setting up a table but I don't know if they were going to lay any food on it as we left before they could finish. The SAS lounge is ok if you are alone, but the BMI lounge is better for you in this case. And the reception staff was polite, we wished her AU Revoir on our departure from the lounge and she replied in kind.
