Does anyone know how this typically works with an all-inclusive?....

The guests are already paying for their food and beverage.  And then the bride and groom are charged on top of that for food and beverage for the wedding day?

its not just for the food...i is for the set up, extra staff needed, etc.

 

could you imagine if it didn't cost anything extra and free private events were available for all guests?  everyone would want a private dinner on the beach, by the pool, etc.

 

also this has been discussed at length already.  you may want to try and search next time.
