(NEW YORK) -- From coast to coast, on British and U.S. airlines alike, Americans are heading to Great Britain in droves.
An estimated 600,000 tourists are expected in London this week because of the royal wedding, and many of them are from the United States. The number of Americans visiting London is up 20 percent this month, thanks to Prince William and Kate Middleton, tourism experts say.
For most U.S. tourists, the journey won't come cheap. Roundtrip tickets start at about $800 and hotel rooms can cost several hundred a night.
But those looking to cut costs can rough it at Camp Royale, London's official wedding campground. For $121, travelers can camp for three nights and have access to hot showers, clean toilets and free tea. They can also glam up that experience by renting luxury tents -- complete with service -- that start at about $1,800 for three nights.
