Hello Cheryl,
Firstly, I wanted to truly say that I'm sorry for you and your family's loss. I do hope that, despite this somber reason for the visit, your group will find plenty of joy and happiness on this trip as well.
I'd be happy to help find reliable transportation! One of my favourite resources is
Transport for Ireland, which is an incredible site that lists methods of travel between two destinations in Ireland. I've inputted a route between Dublin Airport and Shannon city hall, and there are a few routes to choose from. There are a few stops and a bit of walking between bus terminals, but it is a very useful starting point.
Likewise,
Rome2Rio is a very helpful website that you might find useful. I've searched for transportation between Dublin Airport and Shannon as well, and it looks like there is a route with just one stop in Limerick, with about a five-minute walk to the next bus terminal.
If you'd like more travel options, including chauffers or taxis, I'd recommend taking a peek at our website for information about
getting around Ireland. You may also want to reach out to
Dublin Airport about travel options, though they may not have an option for getting a shuttle directly to Shannon.
Do any of these options work for you? If not, please feel free to reach out and let us know more about what your group may need.
Warmly,
Rochelle
