The Organisers of All Together Now have apologised for the issues that arose during this year's festival.
Large numbers of ticket holders complained about huge traffic delays getting in and out of the site, and an apparent wasp infestation.
Those behind the County Waterford festival were slated online for refusing to acknowledge thousands of tweets about chronic traffic issues on the first day of the event.
Now, three weeks later, organisers say they are "truly sorry" for "the issues that arose this year’s festival".
"We are absolutely and fully committed to making sure" they "are not repeated", they said.
"We have taken in every comment, every email and are carefully taking note of where we need to improve".
"We have met and are working closely with An Garda Siochana and our other partner agencies to ensure that the traffic experienced travelling to this year’s festival does not happen again".
"We are deeply disappointed that some areas of this years All Together Now fell short of expectations".
