I am renting from Hertz in Ireland for a 5 day vacation. I had a couple of questions that hopefully people can help with.

A) I was wondering how the mobile Wifi worked. Is it reliable? Reasonably fast? 7 eur a day seems like a great rate. also not having to deal with returning via shipment seems really good.

B) Also how do road tolls get charged back to you? I'm doing Dublin > Killernay > Galway > Dublin over 5 days.

C) Should it get the total CDW Insurance? I looks like CDW is required along with theft. At least online it was forced on me.

Thanks in advance.
