When we were there in 2013, the Saturdays were brutal, but Sundays weren't too bad, really. During F&W Future World always seems like a ghost town in comparison lol. If I had to pick a weekend day to go, regardless of which weekend, Sunday would be my choice. Friday evenings and Saturdays are just too crowded for me.
I felt like the evenings got super busy, when people starting getting into drinking mode. I stuck our 5 year old in a stroller so we could navigate the crowds because it really was that tight. Of course, we still really enjoyed it, despite the masses.
Totally depends on what Sunday you go. We have been to F&W 8 times during various weeks. We have found that the closer to the beginning and end of the fest are when the crowds get heavy on Sunday (the first and last Sunday are packed)...otherwise, they are totally manageable. Friday and Saturday nights are crazy packed, but we have still enjoyed it. The best time to do is during the week.
