I have been using Park N Fly Plus for about 5 years. They have covered parking (self and valet). I always book on website or app. Rewards are same as other, free day for 7 days paid. I have rarely paid for parking when going on vacation. I have been using the valet lately, it's nice to be dropped off first and head home. If you have AAA I believe you get 10% off, if you are Platinum member, you get 15% off. The only times I have some issues is at international terminal. You have to request a shuttle.
