The best family-friendly activities in Mainz for parents and kids (Updated August 2026)

Cool Destinations wants to make your searches as relevant as possible. That's why we offer many ways to help you find the right experiences for you.

On some pages, you can select how to sort the results we display and also use filter options to see only those search results that meet your chosen preferences. You'll see explanations of what those sort options mean when you select them.

If you see a Badge of Excellence label, the award is based on average review ratings, share of bookings with a review, and number of bookings through Cool Destinations over a 12-month period.

The importance of any one factor over any other in a sort order varies, and the balance is constantly being reviewed and adjusted. We're always updating our systems and testing new ways to refine and improve your results to make them as relevant as possible to meet your needs.

Cool Rewards

• Cool Rewards is a loyalty program operated by Cool Destinations. Rewards may be earned by any eligible person holding a Cool Destinations account, subject to the Cool Destinations customer Terms of Use.

Earning rewards

• Rewards can be earned by making bookings on the Cool Destinations website. You will be able to see the value of the rewards you can earn during the booking process.
• Earned rewards will be issued in a pending state and will move to a confirmed state 24 hours after the start time of the experience.
• Earned rewards will be available to redeem once they are no longer in a pending state.
• For bookings that are moved to a different travel date, the rewards will be redeemable after the amended travel date.
• If a booking where rewards were issued is canceled, the earned rewards will not be redeemable and will be moved to a canceled state.

Redeeming rewards

• To redeem rewards, you must be logged into your Cool Destinations account.
• Any available rewards will be automatically applied the next time you make a booking, and their value will be deducted from your order at checkout, unless you choose not to apply them, which requires you to indicate this via the toggle switch. Bookings made using rewards are subject to the standard Cool Destinations Customer Terms of Use.
• You will not be able to redeem only a portion of your available rewards at checkout. It is only possible to redeem all or none of your available rewards.
• There is no minimum order value required to redeem your rewards. This means that you can pay for 100% of your order with rewards.
