I've always had a day dream of doing it, but I never did.
I know 3 people who have and said they loved it, they said it was an amazing experience.
I want to do it someday but dont know anyone to do it with, and dont know if I could take 4 weeks off from work hehe.
Its a dream though.
My husband and I have gone up and down the East coast if that counts. It was awesome, that is what we did for our honeymoon. We went and visited a lot of the beaches and had a blast.
