I think Sat is the best day. Kids entry is free. The rodeo (my favorite) is free. If you get there a bit early like 3 your unlimited ride pass will be well worth it as there are no lines for the kiddos. After 5 lines start to add up. There are size limits on kids so we got a single point pass bracelet for when an adult needed to go with a kid. Bags are checked at entry for safety. Hands stamped so you can go in and out. We usually park on home street and walk no problem.
