Weekdays, less people, more you know what......Ya, best to go on weekdays or middle of the week. Go on weekends, is usually packed. It has been quite awhile I didn't go there, but when I went there during weekdays and not any holidays at all, I can somewhat say, I had the themepark to ourselves. That was like 10 years back
Is getting more crowded nowadays. Not really fun anymore and the rides are never upgraded. Look at the Go Kart, is pathetic.
Some can even die off in the middle of the fun race. Is slow too.
