The good news for many travelers is that more hotels expect to offer wi-fi in 2012.
The bad news is that some may start charging for it.
As hotels try to improve guest services, some full-service hotels may adopt a two-tier pricing system for users of wi-fi.
Casual users who just check e-mail may pay less, while so-called "power users" would pay more.
Start paying attention when you check in.
