I'm green with envy, enjoy every minute of it,

You lucky duck.
Have fun.

Lucky you! Have fun.

Your avatar made me laugh so hard I spit my coffee out!

Have a lot of fun

That sounds like a lot of fun. Enjoy yourself.

Have Fun!

my goodness, that sounds like such a fun and wonderful thing. I wanna go....I wanna go.

Wish we had things like that, but our town is just too small.

This sounds like a great retreat. You will get a lot done, get lots of ideas just in time for the next one. Hope you are having a blast!
