My 16 y/o was invited to go up North to visit a school friend for a week this summer. Actually he is leaving this afternoon to fly up.

The boys parents are uber wealthy, like blows my mind wealthy. Money is no object with these folks.

I have sent him with pocket money to pay his own way for whatever activity they do while there.

I would like to send a Thank you note with my son, I wanted to enclose some additional cash, with a note explaining that we wanted to offer something to offset the burden a 16 year old boy will put on them food wise.

I am just not sure how to word the note and if I am being rude offering, my common sense is telling me this is a kind thing to do, I just do not want to across wrong.
