Yosemite

Get on google earth and look at the uploaded picks so u can layout ur route as to what u really want to see.
I would think 2 days would be plenty from the car.
You can walk up to the Lower Yosemite Falls
I went last year. Kings Canyon, just south of Yosemite, was a nice ride too.

Take 3 days. We did this about 8-9 years ago. Same thing short walks and car.
Go down to the south side of the park to Wawona and the giant redwood area.
Then stay at the lodge at the falls in the valley. Check out the sights in the valley and walk to all of the falls.
You can see people climbing the walls on some days. Be sure to check out what is going on with the park rangers. The hotel has info.
Tubing in the river if that is your thing. It is pretty awesome.
Then take a ride up to Hetch-Hetchy reservoir and and then up to Taloumme Meadows and the pass. All awesome spots. We went out over the pass and then down to Death Valley to Vegas to end our trip.
Yosemite is probably one of the most beautiful places on earth.

Most places you stay outside the park are going to entail a drive of an hour or so to reach the valley floor, so keep that in mind when planning your time.

I've twice stayed at Hotel Charlotte in Groveland. This is on Hwy 120 and is a great jumping off point for a visit to Hetch Hetchy.

20+ years ago I stayed at Cedar Lodge in El Portal (Hwy 140). This is much closer to the valley floor than Groveland.

I know there are places to stay in Fish Camp (Hwy 41) and Buck Meadows but I've never checked them out. I'm sure Tripadvisor has a lot of information about other non-park lodging.

Depending on how much time you can spend in the area I'll throw out another possibility. I've twice stayed in Lee Vining. The tufa towers in Mono Lake (there at Lee Vining) are very interesting. Bodie State Historic Park (a gold mining ghost town) is nearby. A couple of days around Lee Vining should do it and then take the Tioga Pass (Hwy 120) over the mountains and down into the valley. If you made the drive early enough you could spend the rest of the day there before heading somewhere for the night. I believe your park pass is good for five days so you could return to the park for additional day trips.

Let me also throw out that the Mariposa Grove of Giant Sequoias isn't expected to reopen until this fall. If you want to see sequoias and have the time Calveras Big Trees State Park is a little over an hour from Groveland (near Arnold, CA).

VRBO we had a two bedroom stone cottage we rented for 5 nights and it 4 stars awesome near west gate easy drive to valley.
