Add American Express (US) to the list of banks dropping Ireland (and other) exclusions as of September. Gold level and below gets $50K of coverage. Platinum and higher goes up to $100K. This is for Amex issued cards. I have not received any changes on my US Bank issued Amex. If you try this route be sure to read all of the T&C of the rental agency. Some are specific about Visa and MC. There will probably be a learning curve and need for modified T&C for some.

I also discovered my Bank of America World Mastercard also dropped the exclusion. That coverage is through Mastercard. It also has a FTF so won't be used any time soon.

I never found Dooley competitive on price, but they do a better job than the others of spelling things out. I can't imagine Enterprise will keep them a separate company forever. The added costs of maintaining two web interfaces, two reservations system, etc. would be too great.

My last trip in April was a mini nightmare at Sixt. Took over 90 minutes standing in line to get a car. I got to listen to dozens of people arguing about insurance costs, not being able to pick up the rental in the husband's name without him, etc. Luckily I signed up for the free Sixt Platinum through World Elite Mastercard (Citi Prestige). When I finally got to the counter they were out of midsize automatics (Ford Focus) with about 10 people processed and waiting for cars to come back. With the status they gave me the Mercedes E250 parked right outside the door. Ended up being $113US for eight days using the CSP for insurance coverage.
