Hi Laurie,
My name is Marlene, I live north of San Francisco, CA and it's too bad you are taking the Grand Tour of Spain in May instead of March 18 - March 31, that's the one I am taking. I too am going solo. You are going to LOVE it. Not sure if you've traveled with GoAhead Tours before, this is my 6th trip and they take such excellent care of you.... So enjoy, have fun and Happy Birthday!
