A two meter cubed volume would be sufficient to hold that much. I would guess that cruise ships store more urine than that, though presumably not separated from everything else humans dump into toilets.
With the qualification 'in orbit', I imagine it is.
I thought they just dumped it overboard but maybe there are some ethical cruises... maybe.
It's fine to dump sewage overboard if you're far enough from shore. Cruise ships treat it to some extent, but ultimately it all becomes fish food.
