I'll be in the August 1st class. I know that it's been mentioned on here before, but does "business casual" for class include like polos and khakis? Or are dress pants and button ups prefered? Also, I know that a tie had been mentioned for the type ride. Is a jacket expected as well, or just a shirt and tie?
Any other tips or recommendations for preparing for class? Is there a laundromat near the hotel that is accessible for someone who won't have a car in Miami?

Thanks for any tips. Looking forward to get training started.
