There's maybe 20 of us who meet at least 2–3 times a year in Dublin, Ireland. These meetings have been helping me develop my skills over the past 5 years that that I've attended, and it has always been very enjoyable. Recommended!
We use the local camera club in a central location. We aim for a spring and an autumn print showing, all arranged via APUG Ireland forum (check it out). It takes about a month to agree a date.
Usually 10–14 meet. It is not competitive and criticism is friendly yet helpful. Mixed level, each one brings 4–10 prints. Takes 2 hours, then we lunch somewhere in Dublin. Usually there's an in-between photo trip to take pictures somewhere, bit spontaneous.
