Same here, traveling alone is time efficient and no complicated decisions, you decide for yourself, though people are not comfortable traveling alone, but i get used traveling alone. The pictures you took seems like a professional photographer what camera did you use? BTW seems like you enjoyed your trip with the business meeting at the same time enjoying yourself over there no doubt it's a worth of a trip. thanks master @nomad-magusfor sharing your travel in Hawaii it made me think going over there too. :)
