Normally the only times that any of the Parks capacity close is during the week between Christmas and New Year's days. And even then they tend to only close for a few hours at a time until a sufficient number of people have left.
One of the key things with an Annual Pass for someone 21 or older you may purchase (for $75) a Tables in Wonderland card which is good for a 20% discount on meals and beverages (including alcoholic) for up to ten people. It is primarily for table service, but some quick service locations allow its use.
In addition to TiW with an AP, you get free parking if staying off-site, and discounts of 10% at many merchandise locations.
Here is a working example, using $100.00 as the original bill to make the math show up easily. Note this is for Table Service. At Counter Service there is no gratuity added.
100.00 - Original Menu Amount
*20.00 - Discount
*80.00 - Subtotal
*18.00 - Gratuity Added based on $100
**5.20 - Sales Tax on $80
103.20 - Final amount charged, takes into consideration discount, gratuity and tax.
Without TiW Discount (and still figuring 18% Gratuity)
100.00 - Original Menu Amount
*18.00 - Gratuity
**6.50 - Sales Tax on $100
124.50 - Total
$21.30 - Savings using TiW Card.
(Note - At Victoria and Albert's the added gratuity is 20% instead of 18%.)
* Ignore the asterisks; they are there only so the columns/numbers line up properly.
