As promised, here's a quick post showing our actual AGDQ costs compared to my projections:
AGDQ 2015 fee: $100 (projected $100 / a difference of $0)
Airfare: $1,343.80 (projected: $1,343.80 / a difference of -$0)
Accommodations: $887.79 (Projected: $896 / a difference of -$8.21)
Dining out: $299.92 (Projected: $150 / a difference of +$149.92)
Groceries: $55.20 (Projected: $50 / a difference of +$5.20)
Total: $2,686.71 (Projected: $2,539.80 / a difference of +$146.91)
Charitable giving: $175.50 (Projected: $253.98 / a difference of -$78.48)
Here's the same data in .CSV format:
Expense, Actual, Projected, Difference
AGDQ 2015 fee, $100.00, $100.00, -$0.00
Airfare, $1343.80, $1343.80, -$0.00
Accommodations, $887.79, $896.00, -$8.21
Dining out, $299.92, $150.00, +$149.92
Groceries, $55.20, $50.00, +$5.20
Total, $2686.71, $2539.80, +$146.91
Giving, $175.50, $253.98, -$78.48
A few points of interest: We did a good job of estimating travel and accommodations costs but overshot on dining out and didn't quite donate as much as we thought we did. Having said that, a fair portion of our dining out expenses was providing food for people who volunteered to help us out (including micro500 and Tompa, and we also ate with Zoast and Vulajin with shared bills), so if people are willing to be generous and allow us to allocate ~$100 of our overage in dining out as giving we're fairly close to where we would want to be.
I'm overall happy with how our budget turned out for this year, but I hope this goes to show you what kind of costs to expect if you want to attend an AGDQ of your own. Please feel free to ask any questions you have about the data here or our experiences. Once again, I'd like to say thank you to everyone who donated - it wouldn't have been possible to do this without you!
