I'm 6'3". Wife is 5'3". 8yr old and a 5yr old.
Youngest sits behind me cross legged. Oldest sits behind her. She can leave him enough room to have his feet down. Definitely workable for short sub-hour trips. Feedback may vary based on whine tolerance of passengers.
Once that 5 year old gets too big to cross his legs, I'll have some trouble though. I'll just have to leave somebody at home
