I believe that you mean "permits" when you say "tickets." The number of permits are limited for both overnight and day hikes (60 and 100). At this time, all available permits for the month of August are fully subscribed. You can check the recreation.gov website periodically to see if any permits are turned in. I would not count on this happening. A lottery is conducted during the month of February to assign permits.
Consider alternate hikes. For example, the trail to Meysan Lake is near the Whitney Trail. It travels through beautiful country passing several small lakes to arrive at a high mountain lake. The nearby Horseshoe Meadows area offers a variety of hikes all through beautiful areas.
