I should probably ask my friends this question, not strangers, but i don´t have any friends so uh, give me advice?

I´m 18, never traveled to another country by myself, feeling a lil scared. Basically i´m planning to visit my ex boyfriend (whom i still love and we´re still kind of friends with benefits). He lives in the country right next to mine so it´s a few hours train & bus ride. I´d be staying at a hotel, and then come over at his place to ya know. Have sex to put it bluntly.
The reason i´m asking this question is because i feel a bit apprehensive. He doesn´t want anyone to know that we´re seeing each other (i totally get that) but then i´d have to…..come up with a really good lie to my parents as to why i´m going away alone all of a sudden? Or do i lie and say i´m with friends? What if they find out? He said he didn´t want anyone to be angry at him because of me lol.
Should i visit him? We´re clear on that our relationship is not emotional, purely sexual, and i´m cool with that. Mostly. I´ll probably miss him a lot and just want him back.
What would you do in my situation? Visit him and have amazing sex and possibly make him change his mind, or not visit him at all and stay at home minding my own business?
