Can you explain how the passes work?
Does the DCP member have to be at the gate to get you into the park?
Can you go to two parks in one day?
Yes because its her maingate. You are given a ticket that is park hopper so you can hop to another park.
"Six passes for three people"
Do all three people have to be there together? What if there are only two people does the third person for that day carry forward to another day?
The other person would not carry on. It would be forfeited.
If I come to visit her by myself for 5 days and she uses 5 of her passes basically the "other two people" options are wasted?
Yes.
