Hi Pauline,
I'm actually on the same holiday an really looking forward to it. I was apprehensive before I booked my first JY holiday like most travellers are.
This is now my 9th trip with JY and i wouldn't keep coming back if they weren't good, met loads of nice people on all my hols.
Give it a try or you'll never know.
Look forward to meeting you on the 28th (hopfully).
Mick.
ps: If you have any specific questions please ask.
