The mystery of Golden temple!

I don't think there are any monsters outside the minidungeons, the way golden temple is formatted at least in jMS is like this: portal to leave, portal for monkey minidungeons, portal for goblin mindungeons, portal to ravana, and portal to swap towns, and the mirror version of the town is the exact same thing except everything's backward. There's only one map on the way to ravana which I'm guessing is just the signup room. Then again, jMS apparently had free access to their minidungeons.

It's the same in kMS, except minus the portal to swap towns.

 Spoiler

The portal in the ss is the Goblin Caves, and if you look on the minimap, from left to right are:
The portal to leave, the Monkey Portal, the Goblin Caves, and Ravana's Temple.

So how good is the exp REALLY

Apparently, at the Blue Goblin cave, I got 40% per 30 minutes on 1x, and take into consideration the lack of the exp curve in kMS. Each of the NPCs at the temple, besides the ones by the portals that allows you to choose a map, and the one that gives you the ticket, and the one that sells pots, give you a quest based on the minidungeon that is recommended for you, they mostly involving killing and picking up drops, so you get some extra exp for that.
