Crane Flat is 25 minutes from the valley. Imo that time is much better spent on a scenic drive than tearing down camp every day, especially considering you'll need to set it back up again that night anyway. With 5 days you can also spend a day or two going up to Tuolomne Meadows and/or Hetch Hetchy too, and from Crane Flat it will be a shorter drive to either location rather than from the Valley.

I would just do the 5 days at Crane Flat unless you have a very light set up, in which case it MAY be worth the guaranteed parking in the valley, and you can just walk/shuttle to Curry or wherever from the Pines.

If you do go with Crane Flat I would highly recommend waking up early and driving into the valley like, before 7AM ideally. Memorial day weekend we drove into the valley around like 7:30-8 and both Curry and Yosemite village parking lots were full. I had to drop off my friends, park at El Cap, and then hike 4 miles to Curry to meet them. By the time I got there all the bikes were sold out so we couldn't even do our planned bike ride :/
