Graham, I have booked for Tuscany at Christmas. I have not been on a holiday with JustU before but have been on two previous singles christmas hols in UK and one summer hol abroad, I found the age mix to be very wide 30's to 80's - think JustU sound to be similar. All got on together very well - all single and in the same boat! I am 59 - going on 21 and tend to get on with everyone - it's a frame of mind thing. Hope this helps you decide. Pauline.
