As someone who also has a nut allergy I haven't really had many problems in the US. As others have pointed out, a lot of restaurants have little symbols that say whether or not something has nuts. I found these very useful. For Asian food I've had Chinese and Japanese food a lot of times in the US and have never had any problems; they're pretty safe options. I can't really say the safety of other Asian cuisines.I will keep that in mind. As I have a nut/peanut allergy Asian food can be tricky and I have heard horror stories of restaurants in the US that refuse to serve people with allergies because they were afraid of lawsuits... I will be using mostly Airbnbs and cooking there is often possible fortunately.
One thing, when I was in Southern California there were a couple of places that cooked some of their food in Peanut Oil. I'm not sure if this is a common thing but it's something to look out for
As someone who really enjoys the Georgia Aquarium (it's my 2nd favourite, only behind Valencia) I'll defend it a little bit. I think the Aquarium suffers from Ocean Voyager being so brilliant while the rest of the Aquarium doesn't hit those highs; but that doesn't mean the rest of the Aquarium is bad, far from it. I found the coral reef area to be very nice, the freshwater area is a bit pedestrian but has some interesting stuff and the Cold Water area with Belugas and Sea Otters is quite interesting. The Dolphin show thoughI have heard from multiple people now that Ocean Voyager is amazing and the rest of the aquarium a bit of a letdown, but that is fine, I will visit multiple other aquariums on this trip, but Whale sharks just sound like something you have to see. Apart from the sharks it is also really convenient to start in Atlanta as there are 4 flights per day from Amsterdam to Atlanta.
