There are buttons you or your kid(s) can press to get the water flowing since it would be a waste to have the water spritzing if no one was there. It's a lot of fun and I highly recommend it! No request spots needed, you just go and have fun. :)
Are small dogs on a leash welcome.
Btw, last I checked, the buttons were slightly tricky to find if no one's around to show you, but my kids did find it eventually by touching every likely surface. (Spoiler: Unless they've changed it, the activation "button" is like a sphere on a stand -- you just touch it with your hand.)
The city turns on the water those times if the weather is agreeable. You do not have to request anything
