Take your son before he gets older and starts his own life. Buy sticks this spring and start practicing, and bring your son with you so he can practice too. The camps wash your clothes every day so you don't need much. Start getting your passports now. Its a really really long flight. If you can afford it upgrade the seats, if not, no worries. Bring a lightweight smaller travel backpack to carry your personal stuff during the day. Bring ear plugs to wear on the plane. Study what the tipping practices are in the camp and the PH's methods of distributing the monies to the staff and be comfortable with the scheme.

Be prepared to be amazed
