In 2012 I was in the same position as many of you, having lost my husband in February 2012. I had never travelled alone, or even for that matter lived alone. I found singles holiday companies through an internet search and booked my first holiday.
I was so scared a few days before departure that I almost asked my doctor to sign me off sick so that I did not have to go and claim on the insurance! Sense prevailed because I really knew that she wouldn't do it.
You are really "on your own" until you get to the departure airport. Unless of course you have someone to travel with you, or take you to the airport. From there on you will have as much or as little company as you wish.
Fellow travellers are there for the same reason you are - it is somewhere they want to visit. Whether it is for the sights, architecture, history, food, culture, you have that in common at check-in.
I am so glad that I didn't call off that first holiday to France which was in May, I thoroughly enjoyed it. The age range, which was from about mid 30's to 80 really didn't matter. I have two holidays booked this year - one of them with JY.
In my limited experience tour managers have been fantastic. The second hotel was far and away better than the first, but the first was good.
Organisation from departure airport - resort(s) - return airport is smooth. Everything is done for you.
All you have to do is choose - read any reviews on the forum that you can find - book - pay - turn up - ENJOY!!
