Matt,
most of the hotel chains have free/$10 per day wireless or wired internet available. If they only have wired access available inyour room, remember to take a Cat 5 network cable with you .
where are you staying ?
Last year the package pokerstars had us staying at the Treasure Island, the email said that the Treasure Island will be the main hotel again but they have another few lined up in case it gets too busy - they will confirm with me shortly. If i remember rightly they had the internet cable in the room last year but as i didnt take my laptop i didnt pay much attention to it or how much it cost.
Hopefully i wont have the time to play a 4-5 hour tourney at the airport so may not need a wireless network card but its always handy to have one just in case if they arent that expensive to own.
