I regularly had dates planned when I travelled abroad on my own but the dates were secondary to my travel plans. I always had my own accommodation and plans. If the date went great and I stayed with them then it's a bonus but I wouldn't put all my eggs in one basket leaving the success of the trip based on the success of the date.
I once was chatting online to a guy in Iceland for a couple of months and when I went to Iceland and met him, it was a bit underwhelming. We hung out for a couple of hours but that was it. I met someone else that night and that was fun.
So go for it but have your accommodation sorted, enough money and plans to see and do stuff you want to do in case it goes belly up.
