According to an exclusive preview from ScreenRant, EA has confirmed that the next game patch will enable vacationing in any world. This allows Sims to travel into any world to take a vacation, including places like Sulani and San Myshuno.
Mount Komorebi is both a vacation destination world and a residential world. When players take a vacation there, as in other vacation worlds, they will need to stay in a rental property. As part of the free base-game update that comes with this pack, players can now take a vacation to any world, not just the vacation worlds, though rental properties will not be available for families vacationing in the residential worlds right now.
