Consider that most of these properties were set up with an Internet connection a couple years ago. Think how differently we use the Internet today as a society than we did even 2 or 3 years ago. Consider how many high-speed connections are required today vs 2 years ago and you'll begin to understand why hotel internet connections are so laggy. Also consider than 3 to 5 year contracts were signed based on the expectation that you would have 20 or 30 business-men downloading email and porn. Now you have 100+ guests downloading Netflix or alternative streams. Every kid has an iPad or alternative device and they are also uploading / downloading / facebooking / youtubing.. You get the point.
It will take a couple years, in my opinion, before the hotels can catch up to the device-heavy society we find ourselves in.
