Hi Mellie.
I am just a wee bit older than you, And I have now been on 8 Just You trips, Like you, I discovered this holiday firm by accident.What I can say, is that they do really cater for the single traveller, and they have a wide range of holidays for a, wide range of interests. The age groups are very diverse, But not on any of my holidays have I found age as a problem, The groups I have been with have all got on very well, Monets Gardens, although not been on this trip myself, I have heard it is a lovely place and extremely interesting.And a great trip to start your Just You experience, But I pre warn you, You will get hooked, All the best and happy travelling.
Regards Andy
