I'm throwing my sister a surprise party for her 60th birthday and I'm
ordering three big trays of sushi (50-70 rolls on each). I'm wondering
how long after getting it home can it sit out safely? I'm bringing it
straight from the restaurant to the party to be eaten. If I have to put
it on ice, I don't know how I'd do that...three big trays ...I'd have
to fill the bathtub with ice to have room for it!

Can anyone help?
