I was recently introduced to the concept of the PLP (specifically in the context of providing a globally-following umbrella policy to my renters' and auto insurance).

After examining the policy and what it adds onto the others (along with the fact that it will follow me globally if anything happens (eg I crash a car while on vacation in Ireland)), why would anyone *NOT* want to carry such a policy over-and-above their others?

In my specific case (and I know it varies by carrier and how they evaluate their actuarial tables), I gained more total coverage than I had had previously, and garnered a rate decrease because the auto and renters' policies coverage limits were dropped.
