Hmmm... so what does this title mean? Well, in my humble opinion, this should not be considered at "Tourist Trap". But since it is already on the list, I want to add my thoughts. To me, a "Tourist Trap" is something where you feel you did not get equitable value for the money you spend. Quite the contrary, I felt the visit to Bunratty was enjoyable and reasonably priced. Please visit my "Things to do" page for more detail.
Unique Suggestions: Enjoy it for what it is! I'm no historian so I have no idea how authentic Bunratty is, nor frankly do I care! It is very convenient (almost on top of N18 near Shannon airport), reasonably priced, fun to explore, self-paced (we did not join a tour), includes a "village" of interesting (although somewhat similar) buildings, and a delightful tea shop for a bit of a rest after climbing the castle steps and walking the village. I was pleasantly surprised at how many rooms were accessible and how unobtrusive the staff were.
I really wasn't anxious to tour Bunratty - it seemed too pre-packaged and touristy...but it was a really great experience. The castle is a re-creation of medieval times, and the Folk Park represents more modern times - the last couple centuries! It was well worth exploring!
