Just left the Radisson yesterday
.
In room like was just said, the network cable is there on the desk next to the bed. That is where I used my laptop for the week. I think that there is wireless in the lobby but not in the rooms.
The wire that was in the room was like 12 feet long. Bringing your own wire is not a bad idea. I actually travel also with a cable like 35 feet or so (homemade).
If you need to get one just goto local store and ask for a "Patch Cable" If you have time, you are better off buying it online, as they are usually much more expensive in the store.
