Do you mean WiFi or highspeed internet access? WiFi is a hotspot and there is no charge as the service is wireless. You will find some hotels offer WiFi, but it is not secure as you can unknowingly "share" info with others. High speed internet access is something else, you have to plug in to access the service, there is a charge of 9.95 per 24 hours.
If you travel a lot, the best service is your own wireless service. I have a verizon card plugged into my laptop. You pay a monthly fee, but you have your own secure high speed internet access everywhere....it even works in my car. There is nothing to plug in and no hot spot to find.
