Oh, and I sent an email to the front office and DS teachers about cutting his school year short due to this trip and his teacher just emailed me a couple hours ago with this:
Hi Brenda,
That sounds like a wonderful trip! I think the only thing that might
make it more educational would be to take a teacher along!

I won't
be able to have his work prepared for him during Spring Break, but we
can talk about the spelling tests, etc. in April.
Have a great weekend!
I thought it was pretty funny

His spanish teacher already put in requests on what I could bring back from Mexico.

The letter I sent mentioned the educational benefits from the trip...they've known about the trip since the beginning of the year so all is good
