Welcome June
Can I suggest you have a look at the couple of video links on here from Lesley and myself Cindy, it might help you. I have done 8 JY tours now ranging from Austria To New Zealand and Kenya. So if I can help at all just ask.
You will be well looked after by your tour manager, the group gels together really well within a short space of time, the ladies outway the Men. You do not have to be alone unless you want to be alone. They are great fun and what fantastic sights in this world I have seen. Have a look at what is on offe and then BOOK IT.
Good Luck
Cindy
