I can still use the same hershey park cup every time I go? Jus pay the refill.

As long as it's this year's cup

Only during that season

Technically only the season passholders cup can be brought and used multiple visits...the daily cup is supposed to be bought daily not sure if the bag checkers would let it through or not.

I'm sure you can, not sure how Hershey would feel about it though. They may have restrictions on something like that

Yes and you will pay a discounted price for the all day drink pass you can use previous year's cups

Yes just pay for the refill and you will be fine if it's this years cup then ur OK but just to make sure you should ask and see
