I have very little experience camping. My wife has had none. She was actually very resistent to the idea but since it was my birthda, she decided to indulge me. So glad she did.
First off we had an a wordclass, amazing, kind, knowledgable, energetic, sociable guide named Lisa. She was amazing! Just really memorable and probably a highlight of my life. She took us everywhere and more. She taught us how to setup camp, showed us the best way to see the stars, led a group meditation, made sure that we we all comfortable and made sure to be aware of everyone different abilities and interest. She was just amazing!
Everything decibed in the trip, you get to see and then some. You get to see/do more if everyone works effectively together and knows common decency. If your selfish and lazy your just going to screw yourself on this trip.
We slept at a camp grounds with shower and running sinks and bathroom stalls. Bring Sandals, would make life alot easier. The tents were fine. Sleeping mats were fine. We used our own sleeping bags. The food was good and simple. It was sandwiches and tacos and eggs and we did get a chance to buy some food at a local restaurant (this is 1 dinner). On the way to yosemite you do get a chance to buy snacks or extra water so you don't really need to do that beforehand.
We are in a big van with a attached trailer. It fit 10 of us comfortably (including Lisa). So you can bring a luggage and bag if you want, there is plenty of space in the trailer and it will be safe during the trip. Campgrounds was next to a hotel where youo can swim in the pool if you wanted to. I was generally too tired to do that at the end of the day. You share the campgrounds with other people but it was generally quiet after 10. But there was a dog one night that just wouldn't shut up, but you can't really do much about that. Bring ear plugs if you are a light sleeper.
I'm not in the best shape but most things I was able to handle with some exertion but Lisa will always make sure everyone is accounted for and never left alone behind. The days are packed! Expect to rise early at 6:30sih and get going by 8. We came back to camp different times at night but usually enough time and daylight to make camp and cook in the dark. Bring a headlamp, it really helps.
I felt like i got lucky with my group. We were diverse but we treated eachother well. it amplified the experience. I would do this again if given the chance, especially with Lisa at the helm!
