According to the article, “The site combines tips on a specific geographic location with the ability to book a hotel room, rather than one site for each hotel company, or an umbrella site like Expedia.” The article also notes that “it represents a movement toward travel destination marketing.”
It looks like Hotels.com has owned Orlando.com for quite some time. DomainTools Whois History tool shows that Hotels.com was listed as the domain name registrant since at least 2003. In addition, Screenshots.com shows that there have been previous iterations of the Orlando.com website. I am not entirely sure how this new website differs from the old versions, but you could check out Archive.org to see what changes were made.
One interesting thing I found was sort of by accident when looking at the footer. I saw the footer mentioned “ © 2015 Asia Web Direct.” I then clicked on the About Us link, and that took me to a similar looking website on Bangkok.com. I would guess that this is an error and the footer will be updated to reflect the Orlando.com website information. However, it was interesting to see that it looks like they are related to Bangkok.com in some manner (Whois records are different).
If you are looking to travel to Orlando, you might want to check out Orlando.com. It looks like a comprehensive website, and it will be interesting to see if there are other websites that follow.
