"There were 100 crew members everywhere," explains the insider, "and people kept complaining they almost got hit by five camera guys everywhere they went. "
Also hampering the special day for guests like Lindsay Lohan, Eva Longoria and nearly 500 other friends and family? The infernal racket! "The helicopters were so loud nobody could hear the ceremony," the insider said, adding that the Kardashian, 30, and Humphries, 26, wore microphones for the taping.
To keep the high-profile wedding (somewhat) under wraps, guests were also stripped of their cell phones; the Kardashian family even provided a "hotline number" to call from the premises to check in on their kids left behind at a hotel.
Still, despite those elements, plenty of revelers enjoyed the romantic, over-the-top night -- featuring a 6-foot cake, a Wolfgang Puck-catered meal, Robin Thicke serenading the couple and speeches from both sides of the family.
