I'll go first!
I've only experienced Kyokushin training camps that are our branch held once a year (and a bunch of other style day seminars), and I absolutely loved them. They were gruelling, rough and utterly exhausting, but it was so much fun and at the end of it was such a great feeling.
They were always held at the same place every year and we get there Friday (sometimes there was a Friday evening session), and finish Sunday at 12pm. They were always varied and covered lots of different themes: kihon, kata, kumite, philosophy, combinations, tameshiwari/breaking, bag work drills, partner work, knockdown training, conditioning, kuzushi/unbalancing/sweeps, advanced techniques, principles that Sosai taught etc.
I loved the early morning 6am one hour of general training/basics in the carpeted room. It was hard, but once you get going the room was filled with such electricity! Kiais thundering through the air, bodies moving, sweat dripping, and a sense of real unison between everyone.
Most sessions we'd walk across the road and train at the park, but if weather wasn't great we'd go to a hall down the road or just at the camp location there was the room we did early morning training in.
Loved seeing gis hung up all over the place, drying off haha.
There were usually about 50-80 people or so in attendance, and we shared 3 or 4 people to a room, bunk beds.
Plenty of fruit and food was provided, and the meals were always just incredible... always made sure to eat a LOT, but not so much that it would disrupt training haha... learned the hard way sometimes

.
The very last session of the camp would always be a beach session, but EVERY single camp I went on it was always cancelled, and every time I was SOOO bummed out, as I love beach training more than I can say.
The camps really tested our spirit to the max... and not only the sessions but the in between times of how much pain, muscle soreness and fatigue we felt. So figuring out the best way to recover well was important. Always had the thought, "HOW could I possibly do any more sessions with this soreness??" And every time, it was fine.
Funny moments: the odd gas releases in those early morning sessions XD, and alot of grumbling stomachs that just wanted food!
And a tradition every Saturday night was the Sayonara party to farewell the camp (even though we still had lots of training the next morning), and each dojo in the training/eating hall had to do a funny skit, act or performance of some sort in front of everyone. They were just hilarious... very creative, and of course karate-based skits were frequent, along with Abbott and Costello style routines, jokes, songs people wrote, embarrassing memories, and even old videos training and breaking were shown. They were a really fun night. Many people drank just that bit too much, and they really struggled in early morning training haha. But our branch chief said yep, you can drink as much as you want, but you have to make it morning training, no matter what! You'll be paying for it in the end haha
Oh and another funny memory, a fellow from my dojo was at his first camp, and decided to drive down the road at about 4:30am to get a massive meal from McDonalds as he was hungry XD. Tell ya what he regretted it at morning training!
The comradery was just awesome... and you'd really get to know alot of the guys in the branch from other dojos. Even though I always felt a bit like I didn't fit in anywhere, they still felt like family, and I still made some great friendships.
I learned a great deal from every camp, not only technically, as different instructors held the different sessions, and you'd get really great perspectives on certain elements of training, but mentally and spiritually there was always something that clicked. Whether it was simply the fact that you got through it in one piece and the strength and perseverance you learned that was within you, or just really the importance of particular aspects such as balance and posture, the ability to say yes to experience, and to always maintain the posture of the beginner's mind, and always be asking what lessons are in this for me specifically (in which the answer may differ for everyone!).
I truly truly miss those camps, and hoping wherever I end up that camps will feature heavily, otherwise I'll just go to other ones
