Having ridden Living With The Land or It's A Small World you may recall how CMs vary the speed of the boats through the boarding and alighting areas. A similar technique can be used to better handle wheelchair guests, including moving some gondolas a little faster here and there under manual control so other gondolas can come to a complete stop somewhere.
Tomorrowland Transit Authority peoplemover exemplifies unsupervised automatic slowing down at a station and picking up speed when leaving, although CMs can do a manual stop in an emergency.
Further improvement is had if wheelchair guests remained facing the side wall or the doors rather than turning up to 90 degrees after entering and having to turn again to exit..
