My advice is to prepare for the worst (crowd wise) and hope for the best. We were staying off site so we planned to get there super early and do as much as we could until lunch (most rides were no lines no waiting, just the amount of time it took to walk through the que to get to the beginning of the ride). I had made an ADR for lunch which we used as our afternoon break so to speak (nice AC and leisurely meal). After our meal we did the parade and then had all of our FPs. It was glorious to just be walking by everyone in the Splash line mid afternoon because we had our FP. For us, waiting in line would have been much more torturous in the heat of the day than in the morning so it made sense for us to do standby in the am and FP in the pm. We headed to our firework spot once our FP were used and yes, it got crowded but we had put ourselves in a good spot that we were comfortable with. After the fireworks we got a quick bite to eat then did a few more rides until closing. It was a fantastic day and it went MUCH better than I had expected. Sure, we were hanging out with thousands of sweaty new friends but all in all it was a wonderful experience and one I would totally do again. With that being said, plan for the heat, be prepared for the crowds and just enjoy the day. I don't think you will be disappointed! Oh, I had made the ADR in case capacity levels started to be reached (we were off site so that concerned me a little) but our particular year (2015) I don't believe there were any closures. Have fun!!!!
