Separate entities to manage vacation rentals?

[Vee L.]

I'm in Houston, TX. I have a few Short-term vacation rentals that owned by an LLC. I have been managing them in this existing LLC. I plan on scaling up and adding a few more of these. Should I create a property management entity? To be more specific, I will only manage my properties for the time being, not for others. I will increase the # of properties by leasing or acquiring. Does having a separate property management entity give limits my risk and exposure? I've heard that when guests sue, they will sue the property management and the owner. Thanks!
