Working with many weddings and events in hotels and restaurants, we would include champagne toasts in the wedding packages as a value-add (so yes, usually no need to splurge on additional toast beverages). For example, at Lake Placid Lodge, a farm-to-table resort that I work with, they include optional specialty cocktail and a champagne toast in wedding packages. The seating chart poster idea on an easel is a great idea and way to personalize your wedding! Looks great especially in restaurants as easels are usually only for very special menus and announcements (but commonly used in meetings in hotel settings).
