Narrative:

Aircraft was cleared to taxi to runway 17 via hotel. Ground advised that 4100' remained at hotel for runway 17. Initially we accepted the reduced length, but while holding for takeoff clearance we changed our minds and requested the full length runway 17 for takeoff. Tower then cleared us to backtaxi and hold on runway 17. I inadvertently taxied onto runway 13 and proceeded to backtaxi. Tower informed us of our error and asked us to expedite clearing runway 13 as traffic was on 3 mi final for 13. We complied and to our knowledge all other operations proceeded normally. Taxiway hotel is at the intersection of runways 13 and 17. If the pilot is not informed or is distracted, it is very easy for him or her to taxi onto runway 13 thinking he/she is indeed on runway 17. Several incidents similar to this one have occurred at GGG. Yet, never during their communications, did ATC mention that hotel is at the intersection of 2 runways. A simple 'taxi to runway 13, 17 intersection via hotel,' would alert the pilot to the situation. Or, when cleared to backtaxi, a 'cross runway 13 to backtaxi 17' would suffice.
