Has anyone used the auto rental consolidator named Holiday Cars? They have been a pleasure to deal with to this point.
Did you mean Holiday Autos? We had a good experience with them, and great price. But bad experience with the actual vendor in Dublin, who'd run out of cars.
I guess my advice would be Holiday was OK - but take the extra step, and read reviews on who they are going through at your pick up point.
Don't mean/intend to scare you off Holiday. Holiday was OK, but the vendor was not.
Wound up renting through someone else, and trip insurance covering the difference.
Holiday Cars seems to be a company registered in Belgium whereas Holiday Autos is out of Munich, Germany. They do not seem to be affiliated. Also check: http://who.is/whois/holidaycars.com/
