This is really just a game of odds. Don't rush out and buy anything.

The odds are low that someone is going to target you and wait until you try to go to your bank online and check balances, pay bills, etc, and then give your packets a sniff. The odds are very low, in fact.

If I were you, I wouldn't think twice about checking my sensitive information over a residential wireless connection, especially if you have to enter a password to connect (thus encrypting your connection to the router and ultimately your banking site.)

When you get to the house you're going to, request they turn on WPA2 encryption on the router, and they give you the key you need to connect to it. That way, your info will be encrypted all the way around.

Best of luck!
