Single rider lines. RSR has a single rider line that is very useful. We have been on it in 10 or 15 minutes when the standby line was 90 minutes or 2 hours. Indiana Jones also has a singer rider line, but it is hard to see. You go up the exit ramp. The Incredicoaster also has single rider.
MAX PASS-- with one day, max pass will be extremely useful. This July, DD and I started one morning going from one ride to the next at DL with no lines at all, but just booking max pass to max pass. We would scan in a ride, and if we had time would pull up and book the next ride before we got on-- if we were on the ride to fast we would book the next one immediately after getting off the ride. It is SO much better than FP+. It is well worth it and it also includes your photopass photos for the day.
Unlike WDW where you have fireworks, fantasmic etc. every night--- at DLR in the "off-season" those typically only show on Friday, Saturday and Sunday. WOC may or may not be every night. No one really knows what will happen with it when it reopens later this year (the platform broke- so it has been closed for an extended period of time). If you aren't trying to get to evening shows, Carsland is beautiful at night! RSR is a totally different experience at night. We always have to ride it once during the day, and once at night.
CS food is better at DLR than it is at WDW. Don't worry about TS since you will be trying to fit as much in as possible. You can get decent food without having to do TS. Allears has the DL menus just like it has the WDW menus. We prefer the CS at CA to that at DL, but there a lots of good options.
Don't skip POTC-- it is longer and so much better and at DLR!
DLR is so much easier than WDW. It doesn't take long to be anywhere in either park. Have a great time!
