Just looked at the TP historical calendars for Easter weekend (good Friday through Easter Monday):
2012: 6, 3, 5, 6
2013: 10, 8, 8, 9
2014: 9, 6, 6, 6
So the 2015 prediction seems reasonable.
Additionally, it looks like the week leading up to Easter is consistently more crowded than the weekend. For example, in 2013 it was a "10" every single day, Monday through Friday, in the week leading up to Easter weekend. In 2014 it was 8,9,9,9,9 in the week before Easter. So even if you're OK with the weekend crowds, the weekday ones might be too much.
Good luck!
