If I put money on a Visa card for my 12yr old daughter to attend the park & purchase food & drinks, will she be able to use it without an adult?

I dont think that will be possible

I've never tried that, but I doubt it. If it's a card with a minor, they'd need the card owner or adult present I think

You should be able to. But if anyone who reads this comment I highly recommend going on the tutsu. Or the ninja. Or even full throttle. Or if it ever works again superman. But do check out batman. It's really fast. And so is Goliath.

No

Get them a Food Pass and no Credit Card need. They have day passes and season passes.
