Mt Whitney Zone Forums Thread Like Summary - Help with info to 2 foreigners to visit Whitney

My husband and me are planning to visit for first time US and we are arriving to Las vegas on August, and he´s so excited about the idea of climbing mount Whitney. But we don´t have a clue on how to get tickets, and to book correctly using https://www.recreation.gov/. It seems to us the main route to go it´s not available for the week we are there. We arrive on August 11, 2024.

Could someone tell us how we can find an alternative to get to the peak? we want to spend one night and do the whole route in 2 days, if not possible, how can we get an option of 1 day?

Please I'm getting crazy trying to understand the booking system in US. And we are travelling from Costa Rica.

If you want to try a 14 thousand foot peak besides Whitney do Mt. Langley out of Horseshoe Meadows. 4000 feet of gain over 9 miles and trailhead starts at 10000 feet. Better views than Whitney and no permit required for a day hike.
