When you begin the selection process, you choose 3 attractions. After doing that the system will pre-select times for you by bundling your 3 selections and slotting them into times that it hopes will be convenient for you. For example, you choose Space Mountain, 7DMT and Peter Pan. The system will pick times for you such as SM at 11:00, 7DMT at 2:00 and PP at 3:30. If those times are exactly what you want, then fine. You'really done. But odds are they won't be perfect. So the system will offer you a second bundle of times, maybe earlier in the day. And if that is not exactly what you want, you will get a third bundled option, perhaps much later in the day. Ultimately, you have to pick one of those three bundles. But after selecting your bundle you will have the opportunity to move each Fast Pass to exactly the time that best suits you...but only if you don't already have a FP booked during that time. So for example if you want SM at 10:00 a.m., 7DMT at 11:00 and PP at noon, you can pick those as long as you don't already have FPs booked from 10:00-1:00. So to avoid that, when you pick your bundle at the outset, you would want to pick the option that slots your FPs as late in the day as possible, thus leaving wide open the morning times and then move your FP times, one at a time, to the earlier times that you desire.
