Does anyone know if a Contiki Tour to Southern Ireland is okay for a couple of 18 year old guys in terms of safety and having other travelers in our age group?

I have been on 3 Contiki trips to Europe & yes you should be totally safe. I am a girl and I always felt safe. You will have an awesome time too! If you are on the May 23-31 trip - maybe my sister & I will meet you!
