I've compiled a report of (almost) all the multi-day events I've worked, as well as how much flights, and accommodations cost. I didn't include Ubers and food, but my food budget doesn't change dramatically from when I'm at home, and I tend to take public transit a lot, or split Ubers with others, so I usually end up sub $50 on transit over each weekend.

I usually book 4-5 people to a room and share 2 to a bed. Occasionally I'm able to find someone who will take a couch or sleep on the floor. It's about an even split between Airbnbs and Hotels, but on average Airbnbs tend to be cheaper and more spacious.

I fly out of a very small two-gate regional airport on the West Coast of Canada, so for international events I will have to connect through a larger airport.

The blue squares (other than the average line) are events I drove to, I couldn't be bothered to dig up exact receipts, so those numbers are estimated. Two events I couldn't find the flight receipt so I estimated.

I didn't include the one-day shows and RCQs that I do because I typically drive to those and they're fundamentally different financially.

All costs are in USD, converted using today's rate (1.33)

Some fun facts:

I was not at home for 40% of weekends
I was in lead roles for 80% of the events I worked
I have worked for 9 different large TOs

The most organized TO was StarCityGames
The highest paying TO was Kingdoms Gaming (MTGSummit)
The most challenging event to work was Dreamhack
My lowest gross earnings over a weekend were $70 from RC Toronto (maybe if Brandon hadn't flaked out of my room plans it would've been higher)

The average accommodations for Thursday to Monday were $120
The average event paid about $961
On average, I earned $536 for a weekend
