Which option should I choose for my 17th birthday!?

My birthday is this week (17 yrs old) and I'm inviting about 5ish of my best friends (all girls).



I want to go to either

1. Six Flags (but only the WATERPARK) I HATE rollarcoasters haha so I'd have to just go on the water rides and I think they have a wave pool?!

2. Chicago (in general) There's LOTS to do in Chicago (like beach, and restaurants etc.)

3. Raging Waves--a HUGE waterpark http://www.ragingwaves.com/index.php

for kids, teens and adults. they have a huge pool and fun rides



Which one would you choose!???

The weather said "Isolated Thunderstorms" and a temp. of 82..but the weather report usually always changes...



So if weather was a factor which would you choose?

and if weather wasn't a factor which would you choose!?



THANKS!!!Which option should I choose for my 17th birthday!?
Go to Chicago! You can always go to a theme/water park and they are always the same, but Chicago is an adventure! Go! Enjoy!
