Yes, there's anOrange office in LT.
The staff there is a bit slow and inefficient, but if you are armed with patience, you eventually get things done...
It's located between main street and "calle el Carmen", you can't miss it since it is the only building in town that has 3 real boats sitting on the roof, as if it were a second floor. If you don't find it, just ask any motoconcho for "la oficina de Orange"...
