In a lap dancing bar, when she see's all those beautiful young eastern european girls she will say yes to anything. only joking best of luck. Do you know what your getting in to
Buy the bubbly in Duty Free! Top of the mountain is probably best bet - as long as Gondola working!
Also, you might wanna book a table for dinner, some of the nicer places do get booked up!
Go up the new four man by the Rila, ask somone to show you where 'Georges Hut' is, get on to the top (its a small platform) and ask her there. If she says no push her off seriously its a good alternative is you cant get up the gondola.
