output: There are many different types of cookies and at Expedia.co.uk, we use them all. Those set by us are called 'first-party cookies'. Those set by our partners and suppliers are called 'third-party cookies'. Third-party cookies enable visitors to our website to see and interact with content such as videos and advertising provided to us by other companies. The same cookies can also help us with website analytics. More on that a little later.
