Both Waze and Google Maps use remarkably little data...exact amount depends where you are driving, but it's in the rangle of 2-10 Mbyte/hpur. So 40 hours of driving might use about 100-400 MBytes. If I were you, I'd probably get the Orange Holiday package, which has 5 GBytes of data. This should be far more than you'll need, at least for the driving.
