That was my original plan since that's how we did Kyoto years ago but they seem to become less flexible on the leave time on the 2nd day so it was shot down (I sent them an email about just getting unreserved spots on a later train and they never replied. But their FAQ says you can't change or pick a time). And the sight seeing pass probably isn't that good for us since we're on a time crunch (and 4 people) so might taxi a bunch of places.
