The brochure is confusing. It sounds like DDP guests, parties under 6, will be getting billed an 18% gratuity on any items paid out of pocket but will be expected to tip appropriately on the included items.
Technically the automatic 18% gratuity, for parties of 6 or more, isn't a tip or gratuity it's a service charge and as such it isn't discretionary.
about time the peney dropped i think there is confusion on disneys side as well
