Basically, it depends on how you do attractions, you can hold all of the following at once (and even have overlapping return times, allow for multiple rerides of the same attraction with minimal waits between):
- DAS Return Time
- Advanced DAS Return Window 1
- Advance DAS Return Window 2
- Genie+ Return Window
- Individual Lightning Lane Return Window 1
- Individual Lightning Lane Return Window 2
- If your Genie+ Return Window is more than 2 hours away, you could also hold a second Genie+ Return Window
Now each of these have their own caveats, but you could potentially have 7 return times at once under certain circumstances. For us when we used MaxPass at DL, it was great, because we would get to the FP return, scan in at our time and get a return time for another and could have a DAS return time as well, so between them, never really had to wait long for any attraction.
Another advantage is many times the return window for an attraction will be sooner than the wait time, for example with Maxpass at Buzz, one time, we went on it, the return time was immediate with a 60 minute standby line.....never did figure that one out, as even the free paper FPs were for immediate boarding, just scan your ticket at the machine and go straight on, yet people waited in the standby queue and at DL, that isn't a very exciting queue until the last few minutes when you are inside.
