I can also relate to the first point - see where you're coming from there.
Interesting second point, especially from your POV having an interest in a travel company. I did read an article the other day (a newspaper, cannot remember which one!) that Orlando remains one of the most sought-after family vacation spots for Brits, even after financial turmoil and crime concerns.
I guess also you have to take into account the demographic - most of my friends are childless and in their 20s or early 30s (Vegas and New York being the more likely destination than Orlando though) and I can't say that they think the USA is perceived as unsafe for tourists. For their own citizens, however? Different story. Not saying this is everyone's opinion in the UK though.
The tragedy at Pulse generally did not affect tourists. If you put it into context, the apparent decline in Orlando this summer is nothing compared to resorts in Tunisia, Egypt and Turkey etc. where acts of terrorism has had a profound effect on tourism (specifically where tourists have actually been targeted and killed) - hotel occupancy rates are practically nothing in some areas. So while I don't doubt that some internationals might think the US is unsafe for tourists, I don't think the safety threat level is the same as countries previously mentioned.
Interesting views though - guess we will have to wait and see how the summer progresses!
