Hello Eddie,
Car insurance and car rental insurance is one of those things that can be considered expensive but extremely necessary at the same time.
Please have a look at our article page on
vehicle rental for some information on places to rent and also the Car Rental Council of Ireland who represents the industry on the island of Ireland. They may be able to answer your questions with regards to CDW and any alternative insurers than the car rental company themselves.
You mentioned AIG as a possible alternative but as you say are more aimed at Irish citizens looking to cover insurance premiums abroad when renting, maybe there is a similar company in the United States that you could contact?
There are some credit card options that cover rental car insurance but not all are applicable for rental here. One thing to also keep in mind is that if you do use alternative insurance from the rental car company, all upfront damage claims require payment from you and you claim these back from your chosen insurer which may take a long time, something to be aware of when deciding to go with another option.
Hopefully, some of our other members or industry partners may have ideas for you to consider too, when where you thinking on coming over to see us?
