the mugs that come with the gold pass are the standard refill mugs. you can refill them for around $2 with regular drinks and I think $2.50-$3(i'm not 100% sure on the price), they would be very similar to the pre-2012 mugs. they are like all post-2012 mugs only good for one year.
the Vip mug/tumblers are a thing they started a couple of years ago, they are $70 and can be added to your season passes. they offer free refills of all drinks(other than ice cream drinks).
