I hope not, at least for those hotels with international customers. There isn't a snowball's chance in hell that I'll use my European provider's data plan when I'm in the US, at $DEITY only knows how many €€ per GB.
To be clear: I'm not in any form condoning the rip-off charging for mobile data. But I think it's worth looking at what the hotels are trying (and generally failing) to do and why they probably want to get out of the business.
When I'm in America I normally pick up a SIM for data (fucking expensive when compared to Europe). I've nearly always had more bandwidth with it than wifi in any of the major chains (a couple of hundred kbit/s if you're very lucky and repeated firewall signups). It really is quite a challenge to set up a reliable wifi environment in a large hotel, which is why is usually isn't available (no matter what they charge). Smaller hotels with one or two access points just don't have the same problems.
With the US mobile market finally maturing I'm sure data SIMs will start getting cheaper and, who knows, they might even introduce wholesale data which will make it easier for non-US providers to buy bandwidth at reasonable prices. In the meantime I may just pick up a T-Mobile SIM that will give me cheap data in the states.
