Thank you!Two separate things.
Your CityPass is valid for a three day ParkHopper, or you can upgrade it for more days.
MaxPass is an option ANY DLR ticket holder can buy for the day, including App's, comps and sign-ins. You purchase it from your smart phone. You can opt to buy it just for a single day, or for multiple ones. It depends on what you plan to do that day. Focusing on shows and parades, don't buy it. Planning to ride as many rides as possible that day, then yes, buy it.
