If the OP is taking a computer, better to make sure the hotels he stays at has free or cheap Wifi. When you use a booking site like booking.com, you can see what they charge for Internet in the rooms and so forth.

With a computer, he can use Skype to communicate back.

One thing though is that a lot of hotels have poor bandwidth. For instance, I just returned from Cannes, staying at a small hotel and the speed for 300 kbps. Podcasts on iTunes would take even hours to download.

So I happened to have a prepaid data SIM from the SFR network and it got 1 to 2 Mbps. Reception wasn't the best at the hotel but when I went out, I was getting as much as 4 Mbps in a Mifi.
