I have another question.  This is pretty much a dream trip for me as well but I'm wondering if your son will handle that length of time.  I know all kids are different but how will he do not being "connected" with his friends and other family members?  I know my son had difficulty with an 8 night trip at 16.  And my 2 nephews at 13 and 16 on a different trip were fighting over the solar charger for their phones for the week.  It's a different time these days than when I was a kid.
