I went through and disabled the entrance fees on all of my small business lots that I'm not actively playing. Doing this is important because that is the only way a Sim not living with you can enter that lot when invited. You would first have to travel to the business lot alone then invite your friends to the lot.
My teen Aaron is very active and I want his friends to be able to meet up with him at the different small businesses that I've added to the game. My Galaxy Arcade's target customer is teens only.
