Thousands are expected to line the streets as Britain's Prince Harry marries his fiancé, US actress Meghan Markle in one of the most talked-about weddings of the decade.
On-street TV screens will show live footage of the event as it unfolds, allowing those who make it to Windsor to see the couple, whether they make it to the front of the crowd or not.
Food stalls, bunting and ceremonial banners will line the Long Walk in Alexandra Gardens, where there will be designated 'viewing areas' for those hoping to get a glimpse of the happy couple, and live entertainment from local groups will be put on throughout the town centre.
A 6,000 space car park area will also be set out, and more trains are due to run on the day to facilitate extra transport.
"Preparations are well underway to make the town look its best and ensure everyone can enjoy this momentous occasion," Cllr Phill Bicknell, cabinet member for highways, transport and Windsor said.
"We expect large crowds of well-wishers and visitors will line the procession route, eager to catch a glimpse of the newlyweds.
"Our main advice for anyone wishing to join us in Windsor for the royal wedding is to plan ahead: pre-plan and book your transport, make sure you arrive early, think carefully about what to bring with you."
Visitors are advised to arrive early to get a space in the town centre, and have been asked not to bring tents.
Folding chairs and 'some form of cover' will be allowed on the day.
Residents and businesses in the immediate area of the procession route can expect to be written to as the wedding day draws nearer.
