Wow, you're a brave lady. I am thinking the park would be a good idea, they can bring kites or balls to play soccer and other games. I think Chuck E. Cheese would be way too expensive, and same with other places like the water taxi, zoo or city attractions. If they like alligators and walking, you can go to the Everglades down south, around Homestead, admission is free and you can stop at the different points of interest and see wildlife and plants, just make sure to pack some insecticide. If they know how to swim, you can try the beach, but it may be a challenge to keep track of 10 kids. I believe Oleta River Park has a nice lagoon, so no worry of rip tides, and they also have hiking trails, I just don't know if there's an admission fee for the lagoon.
