I've used PL to get amazing deals on rental cars many, many times and always have been pleased with the car I've got.
The only downside that I had to learn the hard way is you will only be allowed ONE driver. You can add another but you will be charged. And I mean even if it's your spouse. Generally, a spouse is a "free" driver (at least always has been in my other rental experiences). May not be a big deal for you, generally on vacation I navigate and DH drives. I had made the res. in my name on our last Disney trip, so I was stuck driving the whole week. Also important to know if you group ever wants to seperate because you'll only have 1 person able to drive.
