I hiked the Mt. Whitney main trail 8/28/2010 and the mountaineer's route 8/24/2013. This year was the first time I entered the lottery, requesting 5 permits. I was unsucessful. I just picked up 2 permits for 8/30/2015 from cancellations on the recreation.gov website. I still need to pick up 3 additional permits.

What is the process for adding the 3 additional permits? Can I monitor the recreation.gov website and book 3 more permits for the same day? I would then have two trips planned for the same day under my name.
