Is Universal crowded Mother's Day?

[Southerndisney]

We will go to Universal on Mother's Day or the next day. We will be probably be doing a bus tour the day don't go to Universal. We will be moving from the Hilton by Universal to a Disneyland hotel Monday evening. Our first choice would be to go to Universal on Sunday and do the bus tour on Monday, but if Universal will be much less crowded on Monday we can switch.
