Every day, cutting-edge technology is being developed that can simplify event planners’ lives, enhance guest experiences and even transport us to distant meeting destinations. Virtual and augmented reality already allows planners with an iPad to accurately display a ballroom to a client, before the event even takes place.

Tech-driven, personalized hotel stays will also become crucial for the planning and hospitality industry as America’s 80 million millennials become the generation spending the most on travel. According to the travel site Lonely Planet, 85% percent of millennials currently own a smartphone, which means that smart controls will be an easy way to appeal to millennial travelers. Millennials are set to beat out the Baby Boomers as the generation spending the most on travel by 2017, estimated at $200 billion on travel each year.

So it’s no surprise that the planning industry is making the most of these latest innovations. Below is a grouping of the latest advancements that are already being road-tested for status hospitality brands and in key event markets. This an exciting time where technology can be a planner’s best friend.

Robots + Artificial Intelligence

You might not realize it, but a robot revolution is taking place in hotels and resorts from California to Virginia. Rising startup, Savioke, has already introduced its robot butler to several leading hotel brands, including Marriott International and Starwood Hotels and Resorts. The ‘butler’ robot is used to deliver small items such as toiletries and snacks to guest rooms. Hilton has also developed its own robot concierge, powered by artificial intelligence technology from IBM’s Watson. At the Renaissance New York Midtown Hotel a futuristic virtual concierge system allows guests to explore nearby points of interest with just a tap to concierge’s screen.

Smartphone Keys & Check-ins

The days of lost and demagnetized key cards may soon be behind us. Major hotel brands are leading the charge by offering keyless entry and digital check-in options. At Starwood, Hilton, and Marriott hotels, guests can use their smartphones to open their hotel room doors and to access guest-only areas, such as fitness rooms and spas. The response from planners has been overwhelmingly positive, with many welcoming these smoother, more streamlined processes.

Smartphone App Controls

Smartphone apps have become standard, but industry leaders are focusing on those technology-driven and personalized experiences in a new way. At the Virgin Hotel in Chicago, guests can use their smartphones to control room temperatures, adjust room lighting, and change the channels on their televisions. All of the smart controls are possible through the use of the phone’s Bluetooth technology. Moving forward, smart controls could allow guests to personalize their rooms in advance via the hotel app, pre-setting room temperatures and lighting preferences, and even selecting the choices for their mini bar.

Sensory Data

According to a panel of experts from this year’s Consumer Electronics Show (CES) convention, sensory analytics will be the next great tool for improving attendee experience. Using wearable tech to track guests’ reactions to temperature, noise levels, lighting and even air quality makes it possible for planners to adjust these factors in real-time to maximize attendee engagement and enjoyment, as well as overall meeting productivity.

Virtual Reality

Virtual reality is only set to grow in both consumer and industry popularity. Whether it’s for leisure travel or corporate meetings, virtual reality is set to revolutionize the way we see the world and in each other for meetings. Ideally, making meeting planning easier and more cost effective than ever. As Facebook CEO Mark Zuckerberg said in a recent CNN/LinkedIn joint interview, “Imagine holding a group meeting or event anywhere in the world. The rise of virtual reality technology will completely revolutionize the way we hold events.”
