Is it safe to use airport's wireless internet service?

1. Is it safe to logon to an airport's wireless internet service?
Yes, it's okay to surf the web wirelessly, but think twice before entering personal information such as banking passwords or credit card numbers when connected wirelessly. Open hotspots are also hotspots for hackers.
Here’s how it works: Though you think you’re logging on to the Internet through a legitimate wireless hotspot such as an airport’s, cafés or hotel’s complimentary Wi-Fi service, wireless hackers are creating look-alike networks to steal your information. The network’s name might be the same as the legitimate name or it might be different. For example, when turning on your laptop at the airport you might be asked if you want to join the "Free Airport Wireless" network. It may be the real thing, or it may be a hacker’s network. If it’s the hackers, your laptop is an easy target.
2.How can I get the most for my money on a short cruise?
You might consider a during-the-week, four-day cruise, instead of a three-day weekend cruise. Because it’s harder for people to get away during the week than on the weekend, there can be less demand for the four-day cruise, so you might get that extra day for less money.
