Dan,

   Here is a partial list of agencies at the GCM Airport (on the

Dan,

For a rental car, starting from the Grand Cayman airport's airline
check-in counters:

1. turn around and walk 30 feet to the glass wall that has the
terminal's entrance doors.

2. Have your SO stay here and watch the luggage.

3. Exit the bilding, and turn left before the terminal's passenger
drop-off/pickup lane. 5 feet,

4.  Walk up the sidewalk, parallelling the road  approx. 100 or so feet
to the street corner.

5. Cross the street. 20 feet.

6. Pass through the row of cars parked here, while heading towards the
strip mall building that's along the left side of a slightly larger
parking lot.

50 feet or so from the road you crossed is the front door to CICO Avis,
which IIRC is first business on the left.  There's others here too.

7. Walk to the counter and Rent the car. 12 feet. Take the short route
back to the exit door: 5 feet.

8. Walk out into parking lot & get in car.  38 feet, on average.

9. Drive back around to the terminal's pickup/drop off spot near where
you left your SO & luggage.

10. Have SO drag the luggage the 20 feet to car

11. Complain to SO about having to walk ~260 feet outside of air
conditioning.
