No! Not the Scooby Doo! D:
They wouldn't get rid of that anyway, it is too popular. The queue line building is massive, and I've seen it filled on days where the rest of the park seems empty. I guess it is the family coaster of the whole lot, not for little kiddies, but not too intense. Even a great ride for those of us who aren't put off by what are supposed to be the scariest of rides.
I would like to see another big coaster, but maybe that's too much to ask. It is in the kids' zone, so they could probably fit multiple kids' attractions in the space left behind. But who are we to speculate without any evidence whatsoever, I guess we will find out.
