I think I will steal your strategy, Pink Budgie. I certainly agree with your logic.
I personally don't mind that it doesn't have FP. I went to WDW for a 2-day trip last summer...the first day we hopped between Epcot and Hollywood Studios but of course all the FPs were gone for TSMM by the time we got there, and we certainly weren't going to wait 90-120 minutes to ride it. If they hadn't had FP, the lines would have been shorter and might have even been tolerable for me--I certainly wouldn't have minded braving a 30-40 minute wait to go on a new ride.
For people who can't stand waiting for 30-40 minutes, I think DL does usually offer Single Rider--back when I went WDW offered it sometimes, but not when we visited it.
