Many of us go alone. There is nothing wrong with it. In fact, it can reduce your wait times with the single riders queue, and often the loading ops will put up a finger if looking for one, like on Drop Zone at PKI, cut my wait time by half an hour.
I'm 37 yrs old. Last year, I flew to Columbus Ohio all by myself, rented a car, visited PKI, Kennywood, SFO, and Cedar Point, I was never bored or lonely.
2 months ago I went to IOA for a day, I had a blast.
You talk to people in line. They see your coaster shirts and start chatting it up.
Being alone lets you do whatever you want, plus it drastically reduces your costs (plane rides, tickets, food, etc.).
This year, I'm flying to SFMM, KBF in September.
When you add people, they just drag you down and complicate things, especially if they are not true coaster fans.
Yeah, go alone and enjoy yourself.
