Start with Pizza Dinner or Steak Dinner, then:

Go for a drive
Get in the drivers seat
Go downtown
Lingerie Store

Note what Ariane is asking for, she will ask for three of four qualities. The possibilities are inexpensive, comfortable, fashionable, and sexy.

Each bra represents two of those qualities:
topless = inexpensive, sexy
wonder bra = fashionable, sexy
sports bra = inexpensive, comfortable
strapless = comfortable, fashionable

Each panties represents one of those qualities:
bottomless = inexpensive
classic = comfortable
boy shorts = fashionable
thong = sexy

There are two right answers, out of 16 choices, and you get three tries to get it right.

(pick required answer)

Agree to drinks at the club with Ariane and Rebecca

Note: if you have not danced with Ariane at some point, do so now, but if you did walkthrough #1 or #2 you already have.

Buy the next round of drinks
Let them continue to dance

The three of you are now in Ariane’s backyard there are multiple possibilities here:

Vote for Skinny Dipping
Say ‘POLO’
Say ‘POLO’

-Note: this “dark maze” is a new addition, if you follow the voices you will eventually tag who you are looking for, Rebecca makes more noise, so following the noise, will likely tag Rebecca. The quickest path leading to Ariane is:

Move towards Rebecca
Move to the LEFT
Let go of Ariane’s breast
Follow her into the bathroom

Instead of swimming, you could also go this route:

Go inside for drinks instead
Wait in the hall
Go to the backyard
Get in the hot tub
Suggest playing “Truth or Dare”
Dare
Have you ever had sex in a hot tub?
Dare
Dare her to steal Rebecca’s clothes
