Jim Langan, executive editor of the Hudson Valley News, said that on Saturday, the Hudson River is going to be closed for a fireworks display.
The Clintons are bracing for any possible power outages too.
"Apparently, they have an army of electricians and carpenters in case there is a thunderstorm and the lights go out," Langan said. "Electricians have been told to wear tuxedos."
Fireworks won't be the only thing shimmering on Saturday night. Chelsea is reportedly wearing $250,000 worth of jewelry.
The wedding cake will be vegan and gluten free. Laura Pensiero, one of Oprah Winfrey's favorite chefs, will reportedly be one of the caterers, for the rumored 500-person guest list.
Bryan Rafanelli, the head of Rafanelli Events and the Clintons' wedding planner, is expected to have some surprises in store.
"Rafanelli will do something really personal," said Millie Martini Bratten, editor-in-chief of Bride magazine, on "Good Morning America." "He likes to channel what is really special about the couple...Maybe they'll write their own vows... They'll be some family moment."
Martini Bratten said she expects that the former president will play the saxophone.
Adding to the elegance, the driveway at the lavish Astor Court Estate, a sprawling mansion built for John Jacob Astor IV where the ceremony will take place, is being widened to accommodate limousines. The portable toilets on site are equipped with hot water and music cost $15,000. Even the electricians working at the event will be high-classing, adhering to a tuxedo dress code.
Security is tight in Rhinebeck, where everyone is prepared for an influx of dignitaries and A-list celebrities. Rumored guests include Oprah Winfrey, Barbra Streisand, Steven Spielberg and Tom Hanks.
One person left off of the guest list: President Obama. He laughed on "The View" earlier this week that even he did not score an invite to the exclusive ceremony.
Editor Langan said that the guest list won't just be full celebrities.
It will be "a little less high profile name and more of...people who are actually friends with Marc and Chelsea, but there are still going to be some A-listers here."
Hotels and wedding staff have reportedly been instructed to act accordingly, ushering the VIP guests from a nearby helipad to their rooms through discrete entrances, like kitchen doors, to avoid the media. The FAA has established a no-fly zone over the town and the Clintons have reportedly hired $200,000 worth of extra security.
"There is a lot of security to protect the protectees, the former president and the Secretary of State, so there will be requirements to follow," said Anita McBride, social secretary under President George W. Bush and chief of staff to first lady Laura Bush. "It takes some real coordination."
Despite the dignitaries and high-profile guests expected to be in attendance, when it boils down to it, the bride and groom are the only VIPs.
"At the end of the day, it's what the bride wants," McBride said. "The bride is your number one dignitary."
