Just returned back last night from a 7 day CL stay, during which we used 3 days of CL FPs, and thought I'd report back.
The program had pros and cons. In retrospect, the biggest pros were the 90 day booking window and lack of tiering for the CL FPs since we were able to ride everything we wanted when we wanted (other than when rides were closed- see below). Riding TT and Soarin', and FOP and Na'vi River, back to back was really great. The HEA viewing area was also spectacular. There were only four other people there, so my kids were able to stretch out and play in the viewing area while people in the Hub were packed in like sardines. DH and I thought this was a highlight, as we often skip fireworks to avoid the crowds with our young kids.
And the cons- we had a couple afternoons with thunderstorms and our FPs converted into anytime FPs for TT, BTMRR, 7DMT, and Splash (separate nights obviously). I'll respond to some of the questions above too in case this gets lost, but those FPs converted into the standard anytime FPs when the FP window began and the ride was still closed. When the rides reopened, as is often the case, the FP lines were quite long and it messed with our schedule in a big way. In short, the con is that you are so booked with 6 FPs that any glitch in your schedule can really throw everything off and make for a stressful night.
The other con was the inability to easily change FPs. I ended up emailing DSS a few times to make changes and was told every time there were no FPs left for the ride or time I was trying to switch to. I understand this means there is not an unlimited CL booking pool, but for the price I thought it would be easier to make changes.
I would only do this for 3 days, as I honestly found our non-CL FP days more relaxing - in part because we knew we had the major rides covered on CL FP days. Planning to use the program again for a November trip, but I'll be more careful about ADRs and not over-scheduling our CL FP days. I have never been as exhausted at the end of a park day as I was on our CL FP days.
I'll post a picture of the HEA viewing area later tonight.
