Of course, the merrymaking stretches beyond Windsor and London. Even if you'll be a bit further north or south on 19 May, there are sure to be festivities taking place.
In Manchester, for instance, head over to Fern House in Bingley for some lunch, a slice of wedding cake, and loads of royal revelry, from 10 a.m. until 4 p.m.
If you're Brighton-based, snag tickets to Stanmer House's Prince Harry & Meghan Markle Wedding Garden Party, hosted by cabaret star Dolly Rocket (tickets are £12 for adults, or £8 for children). The gorgeous estate will, of course, air the wedding at noon, but the merriment will stretch from 10:30 a.m. until 3 a.m. on 20 May.
