For what it's worth, I did not notice any cigarette smoke odor in the lounge when I was there a couple weeks ago. That sounds like a one-off...some idiot lit up in the lounge.
I look at the 6AM breakfast opening as a huge "pro". Lounges that don't open until 7AM are a bit annoying, especially if the full spread isn't ready to go at 7AM on the dot.
Does the outdoor balcony face the right way for the fireworks? I didn't pay close enough attention.
