Where does the room for you come from? Are there empty seats now, with that 135 wait, in order to shove you in there?
Do you have a spouse, family? Are there other people who right want to be shoved in there too?
Now the number of people trying to shove themselves on the ride is everyone managing to ride the ride this way +1 (you) + 2 (family) + [unknown amount of other people on WDWMagic who would do this too].
And this is supposed to happen without creating a negative experience for everyone that is still managing to ride the ride.
Please explain how you accomplish this magical feat without making the wait time longer for someone, or outright taking their spot?
Um, actually yes. There are often empty seats on rides.
One means to fill them is called "single rider." In the before times, instead of letting a seat go empty, I happily sat next to strangers. I mean, all of us pretty much do that all day at WDW anyhow, so why not? I don't care about the picture. I can take a picture just before/after the ride if I'm so inclined.
I always saw SR as me doing everyone else a small favor, because it makes the line shorter for everyone. It is a bit like that old game Tetris. Efficiency is awesome! And I've met some really cool people via riding solo. The last time I rode TT SR, I met a senior-aged couple that were first time riders! I was able to answer their questions, ease their concerns a little. they shared their enthusiasm with me! Very sweet people! Seeing the ride through their eyes gave me a fresh perspective. I very much hope when I get to be their age, that I am equally adventurous!
As for going to WDW with younger family: if we were eligible to use SR, we did. Everyone in SR just has to be 7 or older and comfortable with splitting up. (If we had children under 7 (or not comfortable riding solo), then we split up or stuck with only FP/rider swap.)
To answer your later question, yes, if everyone did SR, the wait would be just as long as standby. If/when that happened, we adjusted, but that wasn't very often.
If many folks don't understand FP, even fewer understand what single rider is. Yes, it is kind of magical. Knowledge is magical. I hope that's why we all participate in this forum, to learn from each other. Though some days, I have my doubts.
