Whenever we've seen WOC (about a dozen times now), we've scheduled for a 90 minute wait. Even if the crowds in the parks are low, the viewing area for WOC still fills pretty full most nights (at least for the first show or if there is only one show that night). We get dessert or treats to eat while we wait, take turns taking kids to the restroom or to ride Little Mermaid, etc. I'm pretty short, so a front railing spot is essential and I'm willing to wait for it. We've been in the back and DH can see fine from there, but I can't see much except the backs of the people in front of me. So, it isn't really about waiting longer than necessary, but waiting as long as needed to insure a great view of the show. Depending on how tall you and your family are, you may not need to wait as long as we do.
