I think the weather was great - so the date would remain. 80-85 at most in the day. Yes, I'd have taken less clothes, and although I wanted a balcony, we do like to take sunset/sunrise photos from our balcony, it wasn't necessary.
We ate almost all our meals in L'Etoile and missed the Grill from Breakfast - we might have tried that. And I'd have taken the 8:20 AM Air France flight home and miss the Radisson Plaza mess.
