Husband help :(

My husband and I are on our honeymoon in Cancun. Two days left. I am 12 weeks pregnant so I'm exhausted and can't drink. 
Last night I retired to our room by 10. My husband wanted to explore, told me he'd be back in an hour. 
He'd had a bit to drink and I asked him not to drink anymore...
12:40 he comes back in the room, stumbling, woke me up from a dead sleep... Starts muttering "whore, slut, asshole, fuck you, I hate you" for about five minutes before he passed out. He's been known to be a mean drunk. 
Then at 3:00am I wake up to the sound of what I thought was water... He is PISSING in the corner of our room! Holding a curtain back, pissing beside a chair and the window. 
I yelled for him to stop and asked "are you pissing in our room?!" He said he was going "on the beach thing" and went right back to bed.
So I woke up at 3:00 in the middle of my honeymoon to clean my husbands piss. 
I am furious. What do I do/say for him to get it?
