Pokepark kanto

We are going this week-end, with tickets for entry in the forest at 10 am. Do we need to be there in advance to enter the park / queue / visit Yomiuriland?

Our kids will be going alone as we were only able to secure two tickets. But tickets are in my name. Should I walk them to the entry so as to show my passport if needed? thanks
