The map you are looking for will probably not be available while the event is still on going.

Incase you are not aware - premium locations drop relatively more event APs than regular rooms.

You can use tools to help you find items or extend the time to find them but you shouldn’t assume that items drop every time you play.

The goal of an event is to get the room to Virtuoso level and all the collection items should drop before you reach Virtuoso.
