I have a split stay beginning Aug 30th. the trip was only me my husband and my 12 yr old son. Now I find out my daughter does not start college until the spring. My older son is suffering from depression. We want to add them to our trip but how do I know if their are park reservations available and the boo bash is Sept 3 , for us I don't know if their availability I am so confused ! How do I fid out this information.
