I have 600,000+ point/miles (?) with my Shapphire card. My wife has never been to Europe (I was ARMY, '60s) .. is there a 'best way' to convert these rewards into a trip to France, Portugal or Italy? (one-not all three) I have never used these rewards for anything before.

No tours, we would simply rent a car and/or take trains between a couple of destination cities within about a 10 day period. I'd appreciate any advice. Thanks. Jim
