First of all I am sorry for your loss, at 34 that's a very hard thing to be dealing with.
Can I assure you that this as a lady is a very safe way to travel, have a look at the two video links on here from Lesley and Myself (Cindy) that will give you an idea of the type of person and what we look like ha ha ha.. I am 53 and have been travelling with JY for 6 years now, I have done 8 tours long haul and short haul in this time. They are really great holidays I have always gone for the action packed style of tour so lots to see and do. A great mix of people which is another reason I like to go on this type of holiday I love the age ranges and the mix of different types of people.. You at 34 would be on the younger side but please do not let that put you off going. PEOPLE do mix in with each other and I can assure you in all my tours I HAVE NEVER spent an evening on my own. I always take a book with me just in case I end up Billy no mates in my room each evening but that has never happened, The age range can be anything from 20-80 I would say the core group is 60-70 or maybe 55-70 I think there are more younger people going nowadays. The ladies always out number the Men.
So please if there is a holiday you like the look of give it a go, just read up what the write up says and if there is a few trips etc you wont be sitting around for to much. I have done 3 USA tours and the are action packed as was New Zealand. More relaxed was Poland,Austrian Lakes, Highlights of Tuscany.
If I can help on anything else just ask. Good Luck
Cindy
