Thanks everyone for all this info. We're not concerned to contacting people back home unless a problem arises. We just wanted to be able to make a call in an emergency.

I've read TomB's blog about the river cruise and found it very informative, thanks Tom. Sorry to hear about the pick pocket incident but glad you posted about it because hubby thinks I'm being overly concerned about things on this trip. I bought him pants, shorts, with zipper pockets and he doesn't want to wear them.
