There is a large pillar standing in the center of the room, and there are two levels. The Hidden Room is a small room full of water. Run all the way through that and go through the next door and you will be in a room called “bottomless hall”. Yeah, once you first enter the main entrance, just go straight back through the door and you will find yourself in a big hallway.
The treasure room should be the room after bottomless hall (I think). How do you get to the treasure room in Kingdom Hearts? If you have opened a KtR room before you beat Sora’s story, and you open it again, one chest will contain the 2nd reward, and the other will contain a random card. After you beat Sora’s story, and you re-open Key to Rewards rooms, there will always be 2 chests.
