I too have gotten it to work before...
I made a tent NPC that would spawn tents with individual insides.

I had the actual tent NPC put down via putnpc2
And when you entered the tent, your last coordinants were saved...
It wasnt exactly fool-proof, you could go in a tent and not come out for a day, and end up stuck on a tree..
I don't remember if I fixed that or not. Now I would have made a level-script that checked with a DB NPC where I would store coordinants and status (maybe dates) of tents to see if the one you are in is still active/in existance...

In the class NPC, I had an

if (created) {
copylevel levels/tents/tent_basic.nw,levels/tents/tent_#v(server.tentquary);
}

NOTE; Dont do it the lame way I did it...
