I am booking a rental car for our upcoming trip to Iceland. Our plan is drive the Golden Circle and the entire ring road and take the normal tourist detours for waterfalls, etc. We will NOT be driving on F roads, but are thinking about driving the main roads in the Westfjords. We are renting from Avis, unless I find something better. For 4 adults + 2 suitcases + 2 carry-ons, what is the best option (best suited for the terrain, comfort):
Skoda Octavia Wagon - seems roomy enough, I'm worried about undercarriage damage
Suzuki Grand Vitara - more expensive
After reading through the forums, I am more than a little nervous about being charged for damage cause by sand/ash/gravel. I usually don't get rental insurance because my car insurance and AmEx have pretty decent coverage. Avis offers collision waiver, death, and theft insurance. Is it safer to just suck it up and get their insurance to avoid significant damage charges? I'm usually good about documenting the condition of the car before picking up and at drop off, but I'm still worried.
How helpful is navigation? It is $200 USD for the duration of our trip. We are fairly capable with a map but wouldn't mind having nav if people find it useful.
Avis offers wifi as an option - $110 USD for the duration of our trip. Anyone have any experience with this? Is it an onboard hotspot or a hotspot device?
Thanks for the help!
