Already been mentioned, but just to clarify... instead of finding/waiting for a kiosk, I was able to text the Grand Floridian to have them set up the FP+ for me. This way, we could do it while eating lunch, while waiting in line for another ride, or even en route to the park we wanted the next FP+ in. It was certainly a time saver, and eliminated the kiosk headache many people seem to encounter. As far as I know, the texting is only offered to club level guests of the CR and GF right now.
Now, this doesn't change the fact that the 4th, 5th, etc FP+ isn't always useful or necessary, but we tended to use it as a "plan b" ... we may not need it, but it was nice to have. Also, as I mentioned, the texting was also good for general questions or other requests. I even asked if they sell funnel cakes in Hollywood Studios at one point.
Personally, I understand how some guests may bristle at these extra perks, but I do think it's just an extension of the services they've always provided. And frankly, the texting service provided a lot more value for our money spent. It certainly has me hooked on club level!
