This will be our first time using the FP+ system, and we are going during one of the busiest times of the year. I got a look at the MDE screen while a friend was booking them for his family's upcoming trip. It appeared as if the system gives you 4 options to choose from, and then you can go back and change them to fit your schedule better if they are available. My question since we are going at a busy time - should I book all the daily FP+ reservations for each day of our trip and then go back and adjust each day after I'm done, or should I adjust and have everything as I want for the first day before I move on to day 2? I guess I'm concerned that if I adjust each day before moving on to the next then maybe some for later days in our trip could be gone.
