Dantes, the BB translocator is safe. The one in OOT is a little more dangerous, actually, because it's on Sister isle and they'll scowl. Just stay at your end of the dock and you'll be fine.

As for BB, you'll want to swim around the wall instead of walking past the guards at the archway. Aside from steering clear of the scattered guard huts, it's really safe in BB. The druid ring in BB is completely safe, and the vendor there is indifferent, too.

Assuming in GFay, you aren't going near the elves, the only dangers you'll run across are the fairies that occasionally wander by. I've only seen them 2-3 times on the direct path to LFay.

LFay and Dagnors are dangerous for all, but in Dagnor's, the dwarf encampment might not be so welcoming. In LFay, the dark elf camp near MM shouldn't be KOS (quite the opposite, actually), but they don't have a vendor, either. The Nybright sisters aren't KOS to me, but they also don't have a vendor.

You might not be KOS to gnomes, though. It's worth checking out.
