My suggestion is you need to do the following:
-Read up on the country you want to visit: their customs, maps and travel brochures to see what's suggested for sight seeing. if travel time is limited , you'd want it planned to see as much as you could.
-Check with travel agencies the cost of fares for a round trip.
-Make sure the validity of your passport covers the trip's duration and more,some countries won't let you in if your passport is soon to expire.
-Same agency may offer a packaged trip including hotel or airbnb.
-Check if you need a visa to travel to the country.
-Call their embassy to find out how long you can stay as a tourist and what the requirements are, example: return ticket required upon entry, visa, cash amount enough for the duration of your stay, hotel reservation needs to be presented.
-Once you decide all this, let YOUR embassy in that country know you are visiting and where you are staying, always a good thing to do in case you go missing.
-Last but not least...make sure you have enough money for the duration of your trip.
-oh and don't travel with too many clothes, just the basic and combinable ones...you may need the space for the things you may buy when you are there.
I think that covers it all ☺️
