Yeah, some of the minors were decent, like Magic Kingdom had some good ones that could build up long waits, but at DHS the only good minor was Tower of Terror (was surprised though), so it's not terrible, but I will probably just wait until I get into the park to book them like I did on my last day since it was very quick and painless. They give you a sheet ahead of time for you to pick your rides.
I'd love to see some pics of the process if you can grab a couple on your next trip.
