Include Multiple level maps in Packaged game

Hi, I have a hotel with 20 rooms I want to package for an Archviz scene. The main lobby and corridors leading to the individual rooms are on 1 level/map. Each Hotel room is another level I load when the player approaches the different doors. Its a load screen to a new level for the rooms.

How Do I package the whole scene with the different levels. Will all the levels be packaged automatically because I’ve got them included when playing the scene?
