HELLO Jeannie
Welcome to you, have a look at the two videos on here one is from myself, and one from Lovely Lesley that might give you an idea of thing's.
There is no AGE RANGE at all for certain holidays I have just been on my 8th to HKG and NZ 31 people (6 Men) age range I would say was 40-75 I am 53.
If I can help you with anything just ask. All my holidays have been different as in locations but they have all been great fun fantastic sights to be seen and a safe and secure way to travel, and great people to meet..
Cindy
