Not sure how your dad gets around, wheelchair or crutches, but if he is not wheel chair bound, go to the view from the seats and see if Section 503 row 4 on the aisle works. You ride the escalator up and walk thru the portal and the seats are to your immediate left. No climbing stairs. It’s going to be hard to seat 8 together but I have four together on the aisle.
Aw thanks all of this information is super helpful. So he's got an prosthetic leg but he's also 6'2 or 6'3 so yeah we were talking about an isle seat. This is so helpful. Thank you so much!
