When we get a one day pass for example we get it for $100 per person would we have to buy tickets if we were to go on any of the rides inside the park or all the activities are free once you buy the 100$ pass to get inside the park.

Ticket prices include all rides.

Most rides and activities are included in the admission price, the only exception being arcade and carnival-style games. PAPER FastPasses are actually "free." You get them by scanning your ticket at kiosks stationed near any ride that offers them. MAXPASS, the digital FastPass system on the Disneyland app, is an additional $15 per person and includes PhotoPass downloads via the app (and totally worth it IMO). Definitely do more research on this topic to learn how it all works as FastPasses are key to having an efficient visit. I also recommend downloading the app regardless of whether you get MaxPass. It's free and full of helpful info and other tools. Food and snacks must be purchased separately, but you are also welcome to bring in your own. I'd never go without at least bringing a water bottle to refill at fountains and restaurants. Final note, go early and be flexible with your plans. Have fun!

Your ticket is all inclusive for rides for one park, if you need to go for both California rides and Disneyland, buy a two day pass. One day is not enough. If you want to bypass the long wait in queues add 'Fastpass' to your ticket for another extra 50 bucks.

Hay, all the activities are free. Except time , 😊, because it's shortly. Ticket is around 130$ from 10 years up.

The rides and most of the activities are included on your ticket but food and souvenirs are pricey.
