The wedding will gain mass exposure at 16 Cinemaxx movie theatres across Germany, providing economical entertainment for anyone looking for a piece of the action.
But there are also a host of settings more befitting royalty.
At Hamburg's Vier Jahreszeiten hotel, visitors can enjoy tea, scones and other treats while watching the ceremony projected on a giant screen, for a total cost of €79.
Not to be outdone, the Ritz-Carlton in Berlin is offering an opulent spread including “royal high tea,” champagne, a “William & Kate” tea mix, sandwiches, scones and crepes for €48.
There will be a live broadcast at the Kuturzentrum in Darmstadt south of Frankfurt, while the city's Centralstation club will have DJs spinning records ranging from Brit-Pop to English rock, house and indie-electro.
The British embassy in Berlin, meanwhile, is seizing the day with a bagpipe performance welcoming some 450 guests to an official party.
For true UK fanatics, the English Shop in Cologne is raffling off a life-sized cardboard cut-out of the royal pair, along with scores of wedding souvenirs. The Broken English boutique in Berlin also expects a crowd of British expats on the day of the ceremony.
Finally, the tourism agency of Norderney, an island in the North Sea, is offering a “royal wedding package,” including a five to seven-night stay in a Friesian lodge, a boat trip, two rented bikes, a candle-lit dinner and, of course, the opportunity to watch a live broadcast of the wedding, costing €870 for two guests.
Germans will also have plenty of TV coverage of the nuptials, as both main public channels ARD and ZDF will broadcast the blessed event live.
