Yesterday I scanned into DL, then went over to CA Adventure. My card got flagged because they have a security lock when you enter one park, leave and then enter the other right away. The CM asked if I scanned at other park to get ROTR, and I said yes, while she overrode the block.
Walked to rope drop by Pixar Pier, they dropped at 7:55 AM, and I made my way to Toy Story Mania. Got there at 7:58, walked to the side where I unfortunately was missing 1 bar on the signal, then at 8:00, got Group 43.
I then proceeded to ride Toy Story Mania 4 times in a row, with 0 wait each time. Also picked up FP's for RSR & Soarin'. By then it was 8:40, and there looked to be about a 10 minute line, so I bailed and went over to RSR, stopping on the way to do Emotional Whirlwind & Little Mermaid. Ended up going into the single rider line since it was shorter than the FP one, and went on it twice. Met a nice lady who was behind me in SR line both times. She was with her son and grandchildren, who rather than go single rider, decided to wait in 30 minute standby line. The 2nd ride she pointed them out in line, and the grandkids looked at her like, "how come she's about to get on ride, and we're still standing in this line?" We laughed about how she'll probably be able to do a 3rd ride before they get through, and maybe she'll even be close to getting on ride at same time.
Then I did Soarin', so I was able to do 5 separate rides a total 9 times in about 90 minutes. I wanted to do Goofy's Sky School too, but it was down when I walked by. I truly think that the park was extremely empty while everyone tried over at DL for the boarding group. Which is actually unnecessary once you scan in. The fact, which I was aware of, that DL had the Magic Morning that day, meant even fewer people at CA Adventure. If you want to cover a ton of rides before lunch, when things start to get really busy, pick a Non-MM day at CA Adventure, and be there for rope drop.
