Planning on coming out Thursday the 30th. Do you think there is enough room for 2 more tents for the labor day weekend?

You would have to be extremely lucky, and get there at the crack of dawn and search to see if anyone is leaving that day.

I highly doubt there will be if you havent already had someone up there to reserve it for you. If you're Just using one tent site you may be able to squeeze two or 3 tents there. There arent many sites and I truly lucked out when I went there last year.
