London, England (CNN) -- In only two weeks, an estimated 600,000 people will descend on London for one of the most anticipated royal events -- the wedding of Britain's Prince William to long-time love, Kate Middleton.
Tipped to be the wedding of the century, thousands of royal wedding tourists have already snapped up many of the 90,000 hotel rooms across the capital.
But if you're thinking of joining the celebrations, it's not too late to bag a room.
"There is still availability for the royal wedding night," said Nigel Pocklington, managing director for Hotels.com. "Around 50% of the hotels we sell still have some availability for that weekend."
But, he warns, "Now's the time to book it, I wouldn't leave it much later than this!"
So, if you're thinking of booking last minute accommodation, keep these helpful hints in mind.
Don't be afraid to upgrade
While some London hotels are already fully booked, some of the capital's pricier establishments have still not filled all their rooms.
If you're willing to pay that bit extra, you can still snag a hotel in the most sought-after locations around Westminster Abbey and Buckingham palace, some at discount prices.
According to Hotels.com, London hoteliers in general are now reviewing their rates to attract more people into the capital as well as releasing more rooms and removing reservations restrictions, such as a minimum number of days if you're booking for April 29.
But the hotel booking website warns April prices are still higher than the average London hotel rate.
Location isn't everything
If you're on a tight budget or don't feel like staying in the center of a crowded London, choosing a hotel away from the processional route or even outside of London could be your option.
"If you're looking to save a bit of money or book a bit smarter, the best thing to do would be to get out of (Central London) and go a few tube stops down the line or even into the suburbs," said Pocklington.
According to London's Transport Commissioner, Peter Hendy, all London tube lines will be running on the day. Teams will also be in place to ensure closures and diversions are managed smoothly.
Most train lines bringing people to and from the capital will be running normal weekday services, with some adding additional carriages. Chiltern Railways, which runs services between London and Birmingham, is even offering free travel to passengers named Kate, Catherine or William.
National Rail has advised people to arrive in London before 10am on the day of the wedding and to check train times and routes well in advance.
Hotels are not the only option, with many Londoners taking advantage of the influx of visitors to make a buck or two by renting out their spare rooms, beds and couches.
According to crashpadder.com, staying in someone's house is on average 83% cheaper than staying in a hotel room, with the added bonus of a free, friendly, local expert -- your host.
Rough it -- royal style
Britain's Prime Minister did it thirty years ago for the wedding of Prince Charles and Diana, and you can too! If you're not too picky about where you sleep, why not camp out -- in royal style of course.
Camp Royale on London's Clapham Common is offering three nights accommodation for £75 ($123).
The Common, 25 minutes by London underground from the processional route, will also have a giant TV screen broadcasting the wedding and will host its own "street party." If that's not enough, in true British style, the campsite offers a free cup of tea to start each day.
