Mardi Gras at Universal: closing at 6?

I am hoping for a Mardi Gras trip because my kids have the whole week off. Crowd calendar shows a 3 for Feb 8-9 2016. Predicted hours show closing at 6 and 7 with parade an hour before. Would two days be enough with these short hours? There are 5 of us. We are all potter and coaster fans but our youngest is 48".

2 days should be good if you are skipping the biggest thrill rides, crowds should be low but the parade is only on weekends.
