Would you want snacks available after wedding dinner?

We’re having a Disney wedding & the dinner/cake is going to be at one of their resorts. We’re just allowing guests to order whatever they want from the menu as some are pickier than others so everyone should hopefully get full enough. After dinner we’re taking guests out on a 90 minute fireworks boat, where we’ll have wrapped cookie favors, champagne, beer, sodas, waters. Should we have a few snacks as well for the cruise? Like chips, trail mix, somethjng like that? Or should everyone be satisfied?
