Going to Iceland next month and looking at $1000 per week for any car that can hold me, my family, and camping gear (and will need it for two weeks). I realized I might be able to use Hertz points, but have never used points for a car rental before. A couple of questions: 1. Can I transfer from either Membership Rewards or Ultimate Rewards to Hertz? 2. Is it possible to check availability without a Hertz account and points in the account? The dates I need are July 30 to Aug 13 from any Reykjavik location (if someone cares to check on my behalf).
