"Hi Dacollari. What follows is a walk-thru for Level 6, Disco. I shared this with a player earlier who didn't find it helpful so I went back just now and re-did it; hopefully it will make sense to you since I re-did the listing to better approximate the order in which the customers appear. Please let me know if this works for you.

First off, after placing flowers on tables, go to podium and have it go off 3 times so it will give you time for the teen girls to arrive.

Sure hope this helps you out! I can certainly try to tweak it, but it does give over an expert score."

that was usefull thanks

I'm so glad you found it helpful, Alar. Thanks for writing.

Hey, I have tried this walkthrough several times and I only get one teen girl. I have done the podium 3 times sat the yappers and still only one teen girl. It may not have any bearing on the outcome but it throws me off a little. Am I wrong?

Yes, it is always just one (green) teen girl.

You're quite right, Jherikeys. There is only 1 teen girl in the first round. My apologies.

thank you for the help. i finally cleared the expert level by 140 points to spare. the guide really helped! i had tried the level about 10 times always coming up about 100 points short.

I'm so glad you made it, Cshort! Way to go! Thanks for letting us know.

thanx for the guide I printed it out, and I'm going to try it.

Thank you very much. That was a tough one but with your help, I made it!! Happy New Year All!!
