How does KMS and JMS players look for newtie/skele parties with mini dungeons?

If you quit a party in a mini-dungeon, would you get kicked out? Because I like splitting maps, but not partying.

I remember when I tried this with an hb mule in the ant tunnel one. When we were both inside the same dungeon, I disbanded the party, but both of us were still able to stay inside the dungeon.
