The first and most important is that we have known for many years the further in advance guests plan their vacation to Walt Disney World the more time they spend with us.
So a decade ago, 20 years ago we used to talk about ticket sales at origin, trying to get people to buy tickets as part of a package, this is -- fast forward 20 years -- this is full resort visit planning, online, very sophisticated tools including booking your fast passes, booking your restaurants, booking everything that you wish to book in advance about your stay, at home, receiving all of that booking data on an RFID-based wristband that you wear while you are in the Park that becomes your hotel room key, your wallet, your admission ticket to the park, etc., etc., etc. And also allows us to, if you wish and you opt in, to know where you are when.
So the fundamental driver that we feel is, number one, like every other enhancement of our product, the better the product gets the more people want to come and visit. Whether that's new attractions, new services, or in this case the combination of planning tools and on-site conveniences that this technology will provide. That -- in terms of its ability to drive volume and spending, because people who plan in advance tend to spend more at Walt Disney World -- are the key drivers of the revenue push behind that.
However, a secondary driver of revenue will be the services that we can now offer on a personalized basis because we know who you are, where you are and, if you tell us, why you are coming to Walt Disney World for this vacation, whether you're a first time visitor, a 50th time visitor, it is your child's fifth birthday, it is a graduation, it's an anniversary. The more you share with us as a guest the more we are able to tailor services and we think get lift in selling those services. So that is the fundamental economics.
