Hi Sylvia,
I like many on here started using JY after losing a partner, its good to travel with other people I believe.
Some of the holidays I've done would really suit you i think but there are many more.
From my experience not in any particular order :-
1. Cilento Coast
2. Croatia Isterian
3. Treasures of Andalucia.
If you consider a touring in future I've done 4 American ones and they have been excellent, think the Golden West is my favorite but not a lot in it.
Doing Americas Heart & Soul (Chicago to New Orleans) in November really looking forward to that as I like the live Music scene especially the Blues Clubs.
