Multi pass question

[TahoeTessie]

I purchased a multi pass for three people. We chose times later in the evening, and now want to move some to afternoon. The modified button will only let us choose the first available time which is early morning. I know there are multiple other times available throughout the day, so how can we modify to get a time that works for us?

I also read that if you have multiple people in your group, and one person does not want to ride a ride, you can modify that one person to a different ride. How is that accomplished?
