I really enjoyed my solo holidays taken with companies that specialise in them.
I absolutely understand feeling nervous about it but I can’t recommend them highly enough. They have a guide who will help you with anything and a whole group of fellow travellers to share in experiences.
They do cost more per person than a holiday for two, but you get more for your money, usually extra planned meals for the evenings and extra excursions compared to the regular couples holidays. Plus a room to yourself?
Actually I met the Man of the Moment on one of these holidays, but now that he is obsessed with Bowls ☹️? and I never saw him all Summer, I shall go back to having holidays like this again.
I mostly went with Just You, and Explore. He went with Solos a lot. They were all very good. I don’t know how companies have fared since Covid but I shall start looking into it very soon.
Do try it. Oh do, do, do!
