I think you're too high.
The equipment all gets trucked out in one or two tractor trailers. We already pay the personnel and own the vehicles. Maybe the total cost there is $10k.
One charter flight each direction is all that's needed to get the team out there. Maybe $100k-$150k.
Need about 60 rooms. I'm pretty sure they fly in on a Friday and out after the game - One night stay. In Vegas rooms are plentiful. I bet they get a rate of about $100-$120. So less than $10k.
I have no clue how feed the team works. But figure $50 per meal per person. Take 120 people and feed them 5 times and that's another $30k.
University will buy about 500 tickets for players/coaches to use. 500 x $50 per = $25,000.
So that's about $200k to $300k in cost.
Also, since we arent going to UCONN now, the hotel and and meals are probably about a wash.
As a comparison point, Hawaii paid UAlbany $150k to play there this year, plus paid for the travel (flights and rooms). I don't know whether Albany chartered or flew commercial.
