Has anyone ever rented one of those mobile wifi units for use abroad (particularly Lake Garda) ?
I've got 2 teens who couldn't possibly survive without it for 2 weeks and I know there'll be free or paid wifi around, but as we're in a mobile home on a campsite I thought one of these devices would be handy (for all of us!) I know you can rent them from Avis etc at the airport but how do they work? (being thick!) and how effective are they?
