Go for it I have my 13th booked for this year quite the Adventurer, you will meet lots of nice people along the way !!! some not so nice but on the whole everyone is in the same boat !! Widowed,Separated,Divorced, maybe a carer for a Sick Partner,maybe Married whose Partner can't face a holiday with them. Whatever ,all ages some maybe younger but have not got as much go in them as the older ones, Enjoy yourself that's what life is all about and you will come back a New Woman.
Good Luck on your Travels
Regards Rosemary
