King Charles III's Norfolk estate has pledged to take on board 'feedback' from residents over gridlock caused by concerts over the Bank Holiday weekend.
Van Morrison, Robbie Williams and The Who took to the stage at Sandringham for four nights, attracting up to 20,000 fans per performance.
But thousands of cars converging on the royal parklands caused long tailbacks around the site, while concert-goers faced delays of more than two hours to exit the venue.
In a statement, Sandringham Estate said: "The concerts provided a boost to the region’s local economy bringing world-renowned performers.
"Feedback from the overall weekend will be thoroughly considered in future plans."
West Norfolk council leader Terry Parish has released emails received from residents.

One said: "We are now in the middle of one of the concert weekends and the disruption and noise pollution is immense.
"Apart from the noise pollution and nuisance, there are thousands of cars converging into the area making it impossible for residents to get anywhere."
Another said: "Traffic blocking roads, two sets of roadworks in Chapel Road at Dersingham did nothing to help with folk trying to get round all the blockages or looking to park and walk up.
"If they are planning more then a serious rethink is needed."
Mr Parish said: "Holding one concert over the Bank Holiday, with appropriate consultation with councillors and residents, would likely be acceptable but four days indicates financial interests were the organisers’ priority.
"I also saw a news story about Robbie Williams planting a tree at Sandringham to save the planet.
"It will take quite a few trees and other measures to counter the carbon dioxide and other pollutants caused by thousands of cars, many stationary or moving slowly."
Promoters Heritage Live, who have a five-year deal to put on concerts at Sandringham, have also said they will listen to "constructive criticism".
Mr Parish said: "All I can ask is for Sandringham Estate to think again about the numbers of tickets available, the number of days events should last for, and the breadth of their local consultation."
