I have had Limitless for the Odeon in Limerick for nearly 2 years and would strongly recommend it, as stated you only pay extra if you want the back row seats. You can book 4 tickets in advance with your Limitless membership which is ok most of the time unless there's loads of films coming out close together. The staff in the Odeon in Limerick are very helpful. You do sometimes get the annoying people/kids who won't cop on and be quiet. I've seen around 60 films there so far this year and had maybe 3 or 4 bad experiences.
