Camping 2018 Questions

I am looking to arrive on Friday and camp until Sunday.  I have downloaded and read the 'All Campers Must Read' pdf, but I have some additional questions.  My apologies in advance if I've missed this information somewhere.

First of all:

• What time does the campsite open?
  
• Where is the entry to the camp site (street address for my GPS)?
  
• Will there be a 'gatehouse' where the camping fee is to be paid upon entry, or do we collect the permit from somewhere else?
• Are the camping spots allocated at the time of checking in, or can you just pick whichever allotment suits us?

Thank you.
