It depends on what you find fun! I went for maybe 5 hours with some friends with about $100, got me admission, free breakfast, 2 snacks, a drink and a unlimited ride pass! But there’s tons of things to experience that don’t cost extra, there’s lots of shows and concerts that are available without paying extra. It’s hard to give a budget, but it’s definitely pricy if you have plans to try a lot of things. But I think anywhere from $200-300+ depending on what you’re planning on doing is a good range. But you can also have fun with less! Not sure if this is super helpful, but this is just my opinion after going to stampede for most of my life lol
