less than $150 (this implies you’re probably commuting and NOT staying overnight)

$150 - $300 (implies driving and staying overnight/flying a short distance & NOT staying overnight)

$300 - $600 (implies you’re flying a short to moderate distance & staying overnight)

$600 - $1000 (this implies you’re flying moderate distance and staying overnight)

$1000 - $1500 (this implies you’re flying a long distance and staying overnight)

greater than $1500 (this implies you’re likely flying internationally and staying overnight)

I probably wouldn't attend no matter what it cost.
