If you're flying, you may want to stay over a Saturday night to save money on air fares. If so, we recommend the Saturday after the workshop rather than the one before the workshop; that way you can either finish up class projects or sight-see with the people you've met at the workshop.
Turn in your receipts in one bundle at the end of the workshop, or by mail a few days later (if you haven't got them all yet when the workshop ends). It'll probably take a few weeks to send you a check.
Some participants will also receive a daily stipend of $75/day; this does not require receipts.
