Does anyone know if there is a day during the week that is typically slower at Universal theme parks?

We are heading back to WDW the first full week of March 2016 with friends and their family wants to spend 1 day at Universal, my family will stay at WDW. Anyway, we are trying to plan our days with ADRs and all that and were wondering which day of the week they should head over to Universal.

The options would be any day between Sunday and Friday.

Thanks!!!

Tom
