Basically, I bought round-trip train tickets, admission tickets, and fireworks show seating tickets for Huis Ten Bosch. The tour guide just handed out the tickets, explained the precautions, and took us to the entrance of Huis Ten Bosch. Then we had to go inside, find the venue, and find our seats ourselves. We only saw the tour guide again when the fireworks show started. During the intermission, they told us we could go to the bathroom. After the show, we had to find our own way back to the parking lot. I saw other tour leaders guiding their groups, but ours didn't. I suggest you write on the purchase page to remind people who are buying tickets, and remind those going to see the annual fireworks event to bring warm clothing and hats, as it gets cold at night. The fireworks are beautiful and really worth seeing, but your neck will get sore from sitting and watching 😅.
