Discover Network, Diners Club International and Merlin Entertainments have announced a multi-year partnership to provide seamless payment experiences for millions of guests at London attractions and across Merlin’s worldwide portfolio, as stated in the joint release. Discover Network and Diners Club will be the preferred payment method across Merlin’s London attractions, including the London Eye, London Dungeon, Madame Tussauds, Shrek’s Adventure and SEA LIFE London Aquarium.

The partnership will also enable acceptance across 100% of Merlin’s other international locations, in both card-present and card-not-present channels. Merlin’s locations join millions of Discover Network and Diners Club acceptance locations across more than 185 countries and territories.

The structural driver is Merlin’s focus on building deeper guest relationships while it continues to grow and welcome millions of visitors each year. The companies position payment flexibility as a core part of making visits easier and more enjoyable.

“At Discover Network and Diners Club, our goal is to be everywhere our customers want to spend, and our customers certainly want to spend at Merlin attractions,” said Josh Atwood, SVP of Global Acceptance at Discover Network.

“At Merlin, we’re actively looking for ways to make visiting our attractions easier and more enjoyable for guests from around the world,” said Dominique Sidley, Global VP Indirect Sales at Merlin Entertainments. She said the partnership expands the payment options available across the portfolio, “giving guests greater flexibility when it comes to how they pay”.

Sidley added that partnerships like this play an important role in delivering the convenience and accessibility guests expect at any of Merlin’s days out.
