What I saw happen is that people would send one member of their group to the cantina while the rest went to lightsabers, then they'd rejoin the lightsaber line after getting the reservation.
I was alone so I went lightsaber reservation first, then walked around for a bit, came back for my reservation, and by then the Falcon's line was 15-20 for the next 2 hours or so.
