Is there any alcohol like beer and/or wine for sale and consumption?

No

There is not but as long as you have your wristband you can leave and come back as you wish.

Probably not, unsure if they allow carry ins either. If they do it wouodnt include booze. If they allow carry ins just match your booze to a color in another bottle. Beer in an apple juice thing, red wine in a vitamin water, etc...

Nope, the only beverage options I recall were a vending machine.

Nope, just energy drinks, soda, water etc.
