Yosemite has a rule that you cannot build fires over 9,600 feet regardless so look at a map and you will see where you want to camp if you want a fire.

If you snag a site it would be simple to base camp for the duration and day hike around the whole basin - the lakes are not that far apart. And you could also go back over the pass and visit Grant Lakes into the bargain. Then you can come back and tell us where all the fish are.
