You will be eligible for a Bambi Band, a wrist worn bracelet used to indicate you are pregnant. You need to ensure you bring proof of pregnancy to the Parks. You can collect the Bambi Band from any Disney Hotel Concierge desk, or from quest services at either park. The Bambi Band has almost the exact same uses and features as the Priority Pass (Green), except you cannot use it for rides unsuitable for pregnancy (these are indicated on the Disneyland Paris App) Find out more about Priority Passes here.
