Most decent attorneys can easily pierce the LLC.Better steps are to make sure you have the correct STR insurance and then you can always add an umbrella insurance policy if you want additional protection. 

If you commingle the assets, you pierce the corporate veil and can effectively negate the benefits of having the LLC because if you're sued they can also now go after your assets too. 

A lawyer might argue you are piercing the corporate veil, but let me ask you this.

If you have any questions about certain neighborhoods in King and Pierce or need input on particular multifamily properties, send me DM.

But first they have to pierce the corporate veil- do you know how difficult that is?

That said, in states like California, LLC protections are sometimes easier to “pierce” if you don’t keep perfect records.

Quote from @Lloyd Pierce: It's our first time in the STR/Vacation home market!  

A trust offers no protection only anonymity.LLC can be pierced be a good attorney and you could trigger the due on sale clause where you would have to pay off the whole mortgage after transferring into an LLC.
