You can either pre-purchase the pass online before you go:

or you can purchase at check-in for the same price.
Mini golf is $7.99 for one round per adult (I believe length of stay mini golf is $13.99). Child's price is cheaper by a smidge.
Bowling is $5 pp, I think. Just be aware that the bowling alley is quite small (its adjacent to the arcade) and the lanes are 1/2 length from a normal bowling alley.
The inclusive meal plan is $47 per adult, $22 per child. Breakfast and dinner are buffet at the Antler Shanty and include a non alcoholic beverage and all gratuities. Lunch is a combo at the Spirit Island Snack shop in the waterpark, at the Crazy Loon at the outdoor pool, or from Northwoods Pizza or the Bear Claw Cafe on the lower level. The buffets are excellent, include a whole kid-sized buffet area with children's favourites, and have literally something for everyone (meat each night includes some form of fish, pork, chicken and usually beef, plus pasta, pizza, a salad bar, fresh fruit, and more). Entrees change daily. The dinner includes a fresh saute station, a make-your-own-sundae bar, and some divine desserts. Breakfast has everything you can picture for breakfast, from eggs served several ways, bacon/sausage, breakfast pizza, pancakes, french toast sticks, fresh baked cinnamon buns, yogurt, oatmeal, fruit, breads, tater tots, you name it...much like a Disney character breakfast buffet (and a character does appear each morning a 8 am....we've never been up that early with teenagers to take that in!). Food at the Antler Shanty has been really, really good in our experience (the quick service is underwhelming, but it allows us to maximize our waterpark time by eating at the lodge).
We find cost of the inclusive meal package is a very fair value vs. the other overpriced, underwhelming options on the Canadian side of Niagara Falls.....one burger/fries/pop meal for 4 at Perkins near the Falls cost us almost $100 with tip a couple of years ago

. And then we had to pay for parking for that meal, too.
