Is my Entity Structure overkill ?

[Satyajeet Dodia]

I need some guidance since i have got diff opinions from diff CPAs on my situation. 

I have three LTRs (in TX) owned by a TX Series LLC. The TX LLC is owned by a WY LLC (as per advice/plan I had received from Anderson Business Advisors).

I have one STR in TX and one LTR in NC that are personally owned.

I have a C-Corp (no assets) as the Prop Manager  to manage leasing and rental collection for all 4 LTRs. This was created as part of same plan from ABA. As I understood that allowed me to have an extra layer of liability protection.  No Employees in the c-corp, just officers.

What should be the simplest entity structure? Do I need to re-structure? I do intend to acquire more LTRs in TX over next 2-3 years.
