my first thought was just go for it
but hten i remembered anytime ive done that ...even though i boarded the plane by myself...ive always had people waiting across the pond that i knew and was comfortable with. and could actually trust tbh. if something went horribly wrong i def had someone to call.
so i guess i cant really claim i def "went alone".
id just say do a shitload of homework. top to bottom. dont treat it as a domestic trip where u just book ur ticket, make sure ur documents are in order and board the plane and stay at a hotel. if ur by urself dig deep into info about that hotel, know what is in the surrounding areas. know what type of neighborhood/area you'd be in, etc.
know the laws for that country, the ins and outs, experiences...especially being black traveling ...as with most things unfortunately, we have to consider other things on TOP of the usual general safety mess.
