Hi Tina,
I'm also 61 and did a discovery weekend last November, plus a Christmas break. I'm going to Halkidiki in May and then Canada in Sept. Whilst I still feel a bit apprehensive, I feel that it's the best thing I've ever done, as I wouldn't go on holiday on my own otherwise and life is just too short to miss out! So yes, you're doing the right thing and what do you have to lose? But what do you have to gain!!! Take care and enjoy
Anne
