Reets always sounds a good place... and, errm, not to bash Omni clubs, but given Rompa's size and Baboon's lag, for PARTIES, it still also seems to me one of the best regular places (gawd there's *room* there folks).
Only other way I'd see to move around in Ent would be either the Engies' warps, or to be Gridded by a level 100+ Fixer. Unless they put these black guards at the sewer's north entrance as well, or it ain't possible to Grid someone this way (oh yeah, I'm talking 'bout the *Fixer* Grid here. Can't bring people there myself, so I can't check this myself)...
Oh well. We'll go to Reets, eh. That ain't such a big way to travel on
