The younger generation would happily shell out more on their hotel room if it looked better on their social media sites.
A study found that 97 percent of millennials will use their social media accounts - such as Facebook, Twitter and Instagram - whilst they are abroad, with 75 percent of them posting pictures or status updates every day.
And around 60 percent of millennials were also happy to pay to upgrade their travel - from things such as boarding early or buying Wi-Fi.
Millennials also preferred boutique hotels rather than opting for name-brand chains. Other generations received their inspiration from magazines, compared to millennials who check out social media for inspiration.
HotelTonight CEO Sam Shank said: "Fundamentally they are different as a generation, which extends to how they travel and how they really travel for business. What they really want is value. They're really interested in spending a little bit more to get a whole lot more versus previous generations who just want to spend the absolute least amount of money as possible.
"This is a generation that grew up with mobile as their first computer, and it was probably an iPhone. In many cases they are very comfortable with it. That is the platform of preference and where they are spending their time, and how they purchase things. We want to be a mobile-first and mobile-only company building and catering to the needs of the mobile traveller."
