Hi Lisa
Now you have been on a discovery weekend. I am sure you have been re assured by the Just You staff. I know travelling alone for the first time can be a little daunting. But I can assure you once you return. You will be saying to yourself, why you haven't done it sooner.
One thing to remember is. That whatever holiday you choose. There will be several people on the trip. In the same boat as yourself, Where they have never travelled alone, Or hadn't done for a very long time. My tip if you do not want to venture to far. Is perhaps try a short coach trip. "Just You" do several different types of trips of about 4 or 5 days. Or even longer if you feel ready for it. The UK has lovely places to visit, But Europe has also so much to offer and experience. And it is good to try out new cultures, foods etc.
I have been on 9 Just You holidays. 8 via coach, And have just returned from My first flying holiday. So if I can do it, So can you.
All the best Lisa and Good luck.
p.s Walking In The Ahr Valley, or the Austrian Lakes are 2 very good trips to start with.
Regards Andy
