As someone that is international who has come to the US for holidays one-two times a year for the past 14 years. Universal is the only reason we now continue to make Orlando part of our trip although the duration is continuing to reduce. Once your water parks were a point of difference..now not so much. You need new and different experiences otherwise your stuffed.
What we see with our friends is a general uneasy with the police/gun violence issues in the US which now has a high media profile and the world has becoming more aware of in the past 3-5 years. I love the USA however it is now not perceived as a safe place, rightly or wrongly by many overseas. I do have an interest in a travel company, all our markets are growing except the US. This is the chief reason why we can not get pick up for US tours.
