Either her, and maybe Elsa. Elsa had the congested/drunk look in Frozen Fever. Seriously, her face-making was funny. I kid, I kid.

Ariel's is all over the place xD I feel like she'd be more playfully irresponsible with drinking...next being rapunzel because she's so naive and then Merida because she'd be like her father

I can see it happening haha

and Anna. Mulan will probably be the sleepy drunk and Anna would be the sloppy drunk

I could see everybody getting drunk except for Snow. Snow would probably go around tweaking everybody's ears for being intoxicated and negligent. :p

I'm surprised Anna is in the lead. she doesn't seem at all like the type to want to get drunk.

Merida would chug it all at once like her dad. Elsa would probably feel the need to drink to be more social.

Oh, definitely.

I could see one of the more "uptight" ladies (Elsa, Tiana, etc.) having "a" drink to unwind and then totally overdoing it.

I can totally see this happening.

I could definitely see Merida drinking recreationally, and Elsa/Jasmine/Tiana/Ariel/etc as well in specific social situations.

That being said, I'm choosing Anna because I could see her just wanting to "have a couple drinks" at a party but then enjoying it too much to stop drinking. I have a friend who's exactly like Anna in many ways, and she has some self-control issues with these things. I could also see Anna drinking to fit in with her cool new friends or what have you. She's very vulnerable, which could open her up to these situations.
