Busch Gardens or other parks?

Our family is new to the area and we're thinking about getting season passes like we had back in Maine for our theme park. It has been the one my family and I have been going to for years and it is something we do weekend over weekend. So, for us, it is a really important decision. BGT is within our radius, so I thought this was something I'd love to know from people who love BGT:

What’s the one memory or experience or feeling that stands out from your visits Busch Gardens? The kind of moment that you think about long after you leave.

The reason we’d love to hear what makes these parks feel special to you is because our son is autistic. His passion is amusement/theme parks and we've created so many memories over the year. So things like location or price aren't a reason for us. We want this to be core memories/experiences. Thanks!
