GSEM has a great new event for gals and girls! Glamping on the Vineyard September 5th - 7th 2014! If it's good enough for the Obama girls it's good enough for yours, is what I say!
Register here! You'll be staying at Camp Wampanoag (cost is $100 per person plus you book and pay for your own ferry tickets.) Here's the description from the GSEM website...
Enjoy a weekend of camping in style as we explore Martha’s Vineyard.
Meet us on the island to begin the adventure. We’ll pick you up at the
ferry station and travel by van to Camp Wampanoag for dinner and a
campfire including gourmet s’mores. On Saturday we’ll see the sites of
the island and stop at the Martha’s Vineyard Wind Festival to make and
fly kites. Be sure to book a return trip ferry ride and we’ll drop you
off on Sunday. Open to all ages: girls must be accompanied by an adult.
