Other Hotels

While we have limited rooms available at the JW Marriott Hotel, there are plenty of hotels in Mayfair with comparable rates and ratings.

You can find options here.

We suggest you book sooner rather than later as there are other events in Hyde Park before the conference, so hotels will become booked up fairly quickly.
