Do you mean the salesperson told you that?
From my understand, it's half right, half wrong.
Some places have open networks, signals roaming through the air, that anyone can use to get online. Other places have networks that require passwords. Others require payment.
PPH, twice so far, has a network down in their lobby area that doesn't require a password. You're not supposed to be able to get it in the rooms. However, the signals/waves don't know what doors, walls, and ceilings are, and both times we've stayed there, I have been able to hitch a ride with their signals and get wifi in my room, for free. Even though I'm not supposed to. I'm supposed to hook into the wall, or pay for the wifi network in the room.
Once when driving home from Anaheim, we stayed at a Motel 6 in OR. They had no internet, but the hotel next door did. You saw more than one person out on the Motel 6 balcony, trying to access the password-only account from the other hotel. I could not guess the password, so we couldn't use it.
And then there are places where you can pay for wireless internet, and I know we stayed at one of those place but I can't remember where...Courtyard in San Jose, maybe? Hmm. I think we just plugged into the wall instead of paying for the wireless.
Your computer has the capability. But not every place has free wifi available for those with capable computers. Half right, half wrong. Total salesguy.
I will give you a tip at HoJo...even though they have cables, they are SHORT. I personally don't like being tethered to the very very top of the bed almost falling in the crack between bed and bedside table, which is what I've had to do when I use their cable. Way too short. So I'd bring my own cable anyway, so that you can move a bit further away. And the cables we've had in their rooms are a bit loose in the connection area b/c people have used and abused the little things that make the connection tighter. Again, I'd bring my own cable.
