Insufficient accommodation in Invercargill was also an issue, she said.
The committee had decided to sell only 4500 tickets and there would not be any gate sales this year, following feedback from festival-goers the venue was overcrowded last year.
Festival chairman John Edminstin said reducing the number of tickets sold by 20% would ensure the venue was more comfortable for those attending.
''We would never have a two-day festival. If it's not broken, don't try to fix it.''
The charter flight tour packages include tickets to the oyster festival and another attraction of the traveller's choice - the Invercargill Brewery, Classic Motorcycle Mecca, The Seriously Good Chocolate Company or Transport World.
Tickets for next year's festival will go on sale at 6pm on Saturday after the festival.
Ms Fowler urged Southlanders to buy their tickets early to avoid missing out, as demand for tickets was increasing every year and there were already about 100 people on the waiting list.
