Depends on my investment level and RP style. Like, if I have 4 heavily roleplayed characters in the same household, each having their own vastly different interests... it can get burdensome and annoying because TS4 does not have an open world. Therefore, if I e.g. want to RP an introvert sim who always stays at home but at the same time I have this utter party animal sim who wants to go out all the time... yeah, it can get tricky because I then constantly need to do these choices on who to spend more time with. That or I just need to turn aging off constantly so I can balance the time between all the different sims and actually achieve what I want to do with them.
If they all just have aspirations that don't require them to travel in different places or I'm not that bothered to fulfill any "check lists", then I don't find it hard at all and actually enjoy big households. I'm not a micromanager so I basically just let them do whatever and just direct them when it's necessary.
Taking care of needs and such don't bother me. It's only if I have more RP-focused goals for multiple sims in a household that it can get bothersome.
