By numbering system do you mean unit numbers and location?

Unit 14 is at end next to pool towards Karakter. Lower numbers are near El Zafaro end. Parking at lower numbers is across from units and higher numbers can park curbside in front of units. I'm not sure where that changes---maybe after 4 units? Check-in office is near El Zafaro end. Maintenance shed is at pool end. Plane watching platform is about halfway between units.

All unit's interiors are the same except alternately reversed.
