We called Caesars Palace and Planet Hollywood to see if they could clarify what "Internet service for one device" meant. Caesars Palace said it was not WiFi, rather a connection via ethernet wire or wireless modem that you bring yourself. Planet Hollywood said the same and that once a device is logged in it would be the only device to receive free connection. Internet would need to be purchased for any other devices. This means if you're traveling with anyone else that has their own laptop, that you'll have to pay for access.
To further confuse the matter, when we stayed at Harrah's last week we were told that Internet would be wired up to the 30th floor, but wireless above that. The reservation person at Planet Hollywood offered the best advice regarding Internet -- ask the desk attendant when you check in about Internet fees so you're not surprised by any charges.
Resort fees always look like a way to increase room rates without actually increasing room rates, and without free WiFi, that's exactly how this writer sees the fees. It looks like I picked the wrong year to let my Diamond status lapse. Oh, well.
