The
DLR Fastpass Encyclopedia is a good place to start.
There are a few caveats/changes since the first post was last updated, primarily in terms of which FPs are connected/disconnected. All attraction FPs are now connected to their respective park's FP system. The nighttime show FPs (F! and WoC), character meet & greet FPs (A&E and Olaf), and Frozen at Princess Fantasy Faire are
disconnected FPs, meaning you can get one of those without impacting your ability to get an attraction FP. Now there have been some recent reports indicating that Olaf may no longer be using the FP system consistently. The Frozen Sing Along (in DCA) was using the FP system (and it was
connected to the rest of DCA), but there was one recent reporting indicating that it might also not be using the FP system consistently. So it's something to check on when you get closer to your trip date.
In terms of the attractions that use the FP system at DLR, it's not that many. You can see a list of all of the attractions that may use the FP system on the
Disneyland.com website. The current DLR FP system operates very much like the traditional/legacy FP system used to work at WDW. As noted in the Encyclopedia, they are enforcing return times, so you should plan on returning during the window printed on the FP. Unlike WDW which had a fairly consistent grace period (15 minutes), DLR does not have a consistent grace period. So if you're late, you may get a sympathetic CM or you may not.
Another big difference between the DLR and WDW legacy FP system is that once your park ticket has been used in one park, it can be used to get FPs in both parks. So let's say you start your day in DL, but want to ride RSR at some point. You can send one person over to DCA to get the RSR FPs, while everyone else remains in DL. You have to use the ticket to enter a park
that day for this to work, but once you've entered DL or DCA you can get FPs in both DL and DCA.
As noted, F! (in DL) and WoC (in DCA) both use the FP system, but they are
disconnected meaning you can get a FP for F! and/or WoC and it doesn't impact your ability to get an attraction FP. The distribute the F! FPs along Big Thunder Trail in DL and the WoC FPs are distributed at GRR in DCA. If there are two shows that evening, they distribute the FPs for the first show first, then the second show. So if you want a FP for the second show, you have to guestimate when they'll start distributing them.
Most of the rides have FP machines near the entrance. There are only a few with FPs machines that aren't located close to the entrance. Most attraction FPs are located very near to the main entrance to the attraction.
- Star Tours is across the walkway between the entrance to Buzz and the Little Green Command Store.
- Haunted Mansion is located a bit set-back from the entrance, close to where the train is when there is a train in the train station.
- ToT is across the "street" near the Red Car Trolley station.
- Splash is by the Brier Patch store, across from the entrance to the Hungry Bear.
- RSR is the most removed, being near the entrance to It's Tough to Be a Bug.
