Ha I know the feeling! I usually take it with the intention I'll have quite a few hours to dedicate to a game then end up watching a movieI took mine to Morocco no issues, apart form falling asleep and not actually playing it ...
I took it to Japan, don't see why not.
When I went to HK the other week they don't even need it out of the bag, only laptops and iPads.
I'm off to New York in 2 weeks and was wondering if I can bring my Nintendo Switch on the plane?
No, but you can probably take it on the plane.
