Do all hotels have wifi?
It would be a little weird if they didn't I know here in Southern California, it's kind of a rarity not to have it in a caf or hotel, but if you're in a bad city, they most likely don't have it.
Not All. :o Most though.
No, but most do. Usually if they don't, they will have broadband and will supply a cable. Unless you get down to the really cheap motels, and I wouldn't recommend staying at one of those.
no i depends how many stars and in some hotels you have to pay for wifi
Most of them do...although in some you might have to pay...
most do, plan a head
most of them
No, and in some countries it's hard to find one
All you have to do is ask them before you book a hotel with them
