Hi Catie,
It's so exciting you're thinking of celebrating your 50th birthday here on the island! I'd love to provide you with some recommendations and tips for travelling around.
If you're not comfortable driving on the left side, public transportation is definitely a good alternative! I've travelled to lots of places on the island just by using buses and trains, and it has always gotten me where I need to go. :) If necessary, you can even take a taxi here and there to get you to places buses don't go, or you can even go on a day tour to certain attractions.
I also recommend looking into public transportation for the places you're planning to stay in, so you can see beforehand if it's easy to reach other places from there. There is a super helpful app called the Transportation of Ireland
Journey Planner, that you can use to plan your trip. For Northern Ireland, you can use the
Translink Journey Planner. The 'I don’t want to drive while visiting the island of Ireland, but how can I get around?' thread has loads of information as well, and I think it might come in handy before and during your trip. You can find it by

The Community is always happy to help you with your plans or look over your itinerary, so please don't hesitate to post any ideas or ideas here. :)
Happy planning, and stay safe!
