Help the Smiths Get Home

Rachel and I had our Mayo visit this week. Mayo requested that we set aside 5-10 days, so we gave them the max, but we were done in 5. After a rough week, all we want to do is go home. We have a flight available tomorrow, and they've waived the fee for changing dates, but the fare difference is $500. We've had a couple of friends offer to help, but would rather this was a tiny burden on a lot of people than a big burden on a few. Chip in what you can, if you can. Thanks.
