Narrative:

We were going to repos the aircraft to the hangar. Ground told us to hold short of runway 30L at taxiway B. We were then cleared to FBO via cross runway 30L, runway 30R, runway 31. At the point where we crossed runway 30R, there was no taxiway on the other side. We called ground and said we were on runway 30R and could we taxi down the runway and make a left on taxiway north. The controller said yes. After we cleared, the controller came back and said our original clearance was cross runway 30L&right and make a right onto runway 31. We didn't remember hearing the clearance that way and did not read it back that way. We were not sure if the controller understood our readback. We were under the impression that we could taxi to the hangar however we wanted as there was no traffic at the time. No conflicts occurred.
