Does anyone know anything about taking the car ferry from Dublin to the Isle of Man? We want to go next May and prices we have found on the internet have been extremely expensive. Thanks.
I have no personal expertise, but it looks like there is only one ferry company that serves the Isle of Man:

If you're buying tickets directly from the Steam Packet Company then there wouldn't be any markup for a 3rd-party seller.
You may want to compare ferry prices with air fare and decide accordingly.
