Depends in which cities she's going.. I moved to Spain few months ago and I'm not really satisfied with the internet services here..
In big cities like Barcelona, there are public wifi spots, but not everywhere.. Some of them are with limited sessions etc.. But if she visits coffee bar or some restaurant, most probably they got wifi.
One little secret that might be fun is teaching her how to crack WEP passwords.
Someone out there may be angry on me, but I don't know if people or ISP's are stupid, they all use wifi routers with WEP encryption. They are sold from the ISP's with some default settings with large password on the bottom, and most of the people are just reading it once, writing it on their PC and living like that, without changing the security type or password.
You can set her up "aircrack" and write her few commands. I assure you that she'll be able to crack a wifi network in around 5 minutes, wherever she goes.
