We stayed here March 2022.  We booked a heated tent cabin for 4 nights.  It had 1 double bed and 2 singles, a storage tower, 1 central electric light, and 1 electrical outlet - this is not advertised, but if you tell them you have a CPAP or other medical device needing an outlet, they will let you know that there is one in the heated cabins.  It was enough to power a power strip, charge our phones, and run said CPAP (LOL).  The beds were comfy and the linens were great.  We requested additional blankets as the comforter on the bed was nylon on both sides and kept sliding off the beds.  We were given old school wool blankets and they were great!  We did adjust the heat often as it would actually get too warm.  

As we visited in the off season, not all of the amenities were available (pool, restaurants), but it didn't bother us at all.  The guest lounge was often crowded and we only spent one evening in there.  Showers and toilets were very clean.  It was still fully booked when we went, but the grounds are quiet are people were very respectful of the park rules.  

This was a great central location to do Yosemite.  We woke up under Half Dome every morning, did the Mist Trail, Vernal Falls trail, and Lower Yosemite Falls trail.  Doing it in the off season was awesome as the number of additional people not actually staying in the park was very small.

Reservations are hard to come by...we reserved in January for March of the same year and got lucky.  Book through the NPS as other sites charge additional, unnecessary fees.  We also recommend packing in food.  There are bear lockers to store it.  Dining in the park is provided by Aramark and is average at best.  We took a trip outside the park to dine in a nearby city and had a wonderful dinner. 

Overall, we would definitely stay here again and again!  It was very peaceful and comfortable.
