I’ve gone to this from the U.K. before (and am again this year) and I’ve done it both ways (tent hotel and normal camp) and in my experience the price this year doesn’t justify it (it’s like €55 more than last time I did it).
I think I’ll just be camping as normal with one hold bag between two of us. Only time I had an issue with that was 2022 when it was SO HOT that lugging our stuff was so unpleasant.
I don't know, the person managing Mad Cool's Instagram is replying to several comments from people asking for Linkin Park. If I had to guess, I'd say they'll be confirmed for both Mad Cool and Nos Alive.
