Hi Marilyn,
Thanks for reaching out.
I have personally not used Go Irish Tours, but perhaps you could read over the customer's reviews on google to get a better insight. There are over 94 verified reviews you can view
here.
I would also suggest that you have a look at our
travel operators page to see if there is someone who can help with your plans. They offer self-drive options and take the stress out of organizing it all yourself.
Let me know if you have any other questions and I would be glad to answer.
