Go for it!!! My Mom had booked a trip and was going to go with a buddy. Well the day before her buddies husband got very ill and she had to cancel. My Mom was torn as to what to do but , kept think about the money she would loose. Well she went by herself and had the time of her life. She has contined to take annual trips ever year by herself , and looks forward to meeting people along the way.
It sounds like there is more reasons to go , places you always wanted to see, plus fabric/sewing/textiles!! Life is to short to wait for all of the stars to allign perfectly. Just go for it!
