AIO Friends plan a trip to visit then cancel

I moved about a month ago 8 hours away from my hometown for the summer. I'll only be here for a little over 2 months and will be back in time for the school semester to start.

This was a big deal for my friends because none of us have ever moved away for anything and in their eyes it felt like I would never see them again. I mentioned to them briefly that they should come visit if they ever get the chance because itll be all of us in a new city and i would be able to provide housing for them while they were here.

They picked dates to come and made a entire list of places they wanted to visit while they were here. They would even ask me about the apartment im staying at and how sleeping arrangements would work since it would be a handful of them coming. Keep in mind, this whole planning thing was a three month long process of them talking about what they wanted to do while they were here, where they wanted to eat, the times they would leave and arrive, literally everything. One thing they did not do was get approval to even come.

Were all in college, all still living at home, and some people have pretty strict parents. The ones who knew their parents would say no just opted out of the trip to not go through the hassle which I respect. But one of them mentioned they were "99% sure they could go". Some background of this person, we have tried to plan multiple things (trips and hangouts), but they would always make us work it around their curfew and time and we would respect it as much as we can then we would cancel last minute because it just wouldn't work out. So two weeks before the trip was supposed to happen, they texted they cant go because their parents wouldn't allow it... they have been planning this trip for 3 months. I blocked out that weekend for them to come and told other people like my bf and sister they couldn't come during that week because my friends would be here. And now because one person isnt allowed on the trip, they decided to cancel it. One person out of 5 people who would've been on the trip...

I told them "im never gonna try to go on a trip with you guys i dont even try to plan one" and i am being so serious about. I still to this day am annoyed because like ????? Youre telling me you planned a whole trip basically and didnt ask for permission knowing that its the one thing that can hold you back. I know i will hold a grudge about this while situation and its pissijg me off just thinking about it. I dont care that they cant come and visit me because i know i will see them again but its more of the principle of the whole thing that genuinely annoys me.

Am i overreacting?

Tldr: friends planned a trip for 3 months to visit and cancelled 2 weeks before trip wouldve happened
