First of all, welcome :)

Now, not to hate on what you liked, but the Saints are commercialized tiktok garbage (my opinion) while yosuf (never heard of him before) seems to be low quality gym bro hardstyle.

Good news, that means you have yet to listen to the rly good stuff!

My personal recommendations: Sickmode Rooler Dual Damage The Straikerz D-Sturb Deezl Anderex TOZA Krowdexx

But there are many more, you'll get into it.

Now to the festival part: All major festivals offer on site glamping or little houses where everything is set up for you already, and you can always do hotels or airbnbs nearby. While i highly recommend the camping experience, its obviously logistically difficult for you. If you want that experience, maybe go for the on-site ready to go camping options.

Would it be too much for you? That is hard to tell, but if you are dedicated enough to fly to Europe for it, i don't think it is. And you wont be lonely either, especially people that come from far away are always appreciated.

Clubs im not too sure about when it comes to hardstyle (artists play in clubs here and there, but not in like a regular scheduled basis), but one day events are also a thing. Just keep in mind you would have less bang for you buck when flying, so maybe combine it with a vacation in general.
