At $16 per person per FP, that is lower than the built-in cost of FP for EMMs. But, the CL FPs have huge problems. They cannot overlap with your regular FPs, so you need to commit to at least 6 hours in the park, which sounds pretty tiring to me and makes it difficult to enjoy some of the other types of attractions, like parades. And they cannot be changed by you. If you want to change them, you have to call DSS and have them change it. I really like moving my FPs around in the app, based on what is available and how my day is going. And finally, they cause lots of problems for those with APs, because even if you are onsite, the system sees it as a separate FP from your onsite stay, so it triggers the 7-day FP limit for APers, *even with onsite stays.*
The only way that I will pay for FPs is if they make my experience significantly better; if they enhance what is my current experience. I would not pay for a bigger inconvenience.
