After having one trip under our belt with fpp I was a little more experienced this year. Here are a few things I did (also referred to mesaboy's link several times lol )
-use those extra fp options if you can, I didn't realize last year you could do this until AFTER our trip. There may not be anything 'good' available but the option is there.
-with that said above, using your 3 allotted fp in the am or let's say before noon could benefit you. Then again, depending on the attraction some of our fast passes are during the time our 2 year old will be sleeping (hopefully) so that opens up some time for us in the morning.
-I just changed our meet Mickey m&g to haunted mansion yesterday....why, well, I've been watching wait times for a few months and while early May could be different I noticed my favorite attraction has a consistently higher wait time than I'm Illini to wait. More so than what I've noticed on previous trips.
-our first night I have wishes fp viewing area booked, but only did so because we aren't entering the park until around 5pm on this day. We could go earlier but since we are driving we should arrive between 12-2 and this will give us ample time to rest, take showers etc instead of storming the parks. It was the perfect time to ride pirates (which is closing for rehab during our trip), let our daughter meet tinker bell and then go see her fly across the sky for wishes! Since it's so late in the day I was ok with giving up a fp for the viewing area.
-I had to book as a single for wishes and use the copy to another party method a few others mentioned. Hubby's wishes fp is 5 minutes later than mine but it's all good.
-I would suggest making 2 lists, the first listing each day of your trip and what your 3 selections are. The second list is a priority list of those selections which attractions have the highest priority to you keeping in mind the popularity of the attraction and booking them in that order. Ex. When booked our SDMT I just clicked 2 other attractions on my list and hit done! Lol I just was making sure the SDMT FP was secure, then went back and amended the other two attractions once I got the more popular ones.
-just remembered that last year we made several times adjustments to our fp. If we were running behind etc. it didn't always work but I want to say that most of the time I was able to move the fp just 30 or so minutes later. We did this quite a bit, there were also times when we would notice the wait time at say dumbo was low when we were there so we rode it and changed the fp we had reserved to something else.
-which brings up my final point, if you find you are not able to use the fp you have, please cancel it. This opens it up for another guest (I think anyway? ) to experience an attraction they may not have been able to before.
