The best idea if you can swing it, would be to get the more expensive of the tickets (I want to say it's around $25.) This type of package/ticket offers every activity for free (included in the price of your ticket) with the exception of the couple things that are not in any package like face painting. The only other thing you would need money for is food or beverages, and anything from the shop- they sell decorations, pumpkins, stuffed animals and toys for kids, etc. But like I mentioned, if you choose the more expensive package you actually save the most money because everything is included and you're able to just walk up and hand your little ticket to them vs. going and buying extra tickets for the additional activities they have available for you to do. It's a really great place, and a lot of fun! You can easily spend an entire day there, and you will want to go back again for sure.
If you want to fees the animals they have (goats, bunnies, chickens, etc) that is $2 a cup but they go pretty far. Food and some special attractions are money but the hayride, games, shows are all free. My kids played in their really awesome playground there for almost 2 hours. Also the store at the exit has a bunch of great fall treats that you can purchase
Almost all the other attractions are free; the only ones that cost additional money are the apple cannon and paintball shooting. You'll need money if you plan on buying food or drinks, or buying anything from the store on your way out.
