Some more information might be helpful to anyone willing to help. How far are you willing to travel? What are your skills? What type of sailing are you looking for: coastal, inland. What safety equipment do you have of your own? What are your expectations of the week?New hampshire might work. I haven't been there in near ten years but I remember it being very nice. I'm currently in Knoxville, Tennessee.
When we hosted a couple who we only knew through SailNet, a fair bit of advanced planning went into having near-complete strangers on our boat for a weekend, let alone a week.
