The GH is convenient (especially if the sky trains actually both operate), but it probably requires more walking than you will want to handle. I’d use WC assistance and book a hotel near the airport. If I recall correctly, the taxi line is close to the domestic baggage claim, so it would seem likely that you can get the wheelchair person to take you to the taxi line. The shuttle line is farther away (upper level). On the way back the next day a cab or Uber can drop you off at the curb right next to the terminal doors. Not sure that wheelchair assistance is available from the curb to the checkin counter.


The international terminal and the AS/AA terminal are connected behind security, but it’s a bit of a trek. Not sure that the WC attendants would be keen to do that to accommodate a lounge visit, and not sure how the logistics work if they do - do they hang out with you for 1-2 hrs or do you have to hope that someone comes back later to collect you, or do the lounge attendants call someone when it’s time to head to the gate?
