Name the portal on the map ExAcTlY how you name the actual portal. And why not biome and directional &/or or something significant. Why make it a mystery you have to unravel each time? ie., bfspawner , treefarm, draugrfarm, sertlingfarm, elder, merchant, spawn, etc. If you are exploring roaming1 and maybe roaming2 that move with you and other end located in your armory so hopping in and out is quick. Put a cart next to it in armory for dumpage and off you go.
KISS. More opaque the harder it is to remember, if use caps randomly adds to confusion.
