There is no reason to ask that question because if you want to have fun ! every day will cost around 500 pluse a day per person ! we spent just under 7 grand ,2 children and 2 adults for 3 nights 4 days at the Polynesian with food tickets and one park per day not to mention the 20 dollar's for valay parking oh ya also the 200 pluse dollers for the Hawaiian lewal the first night for the two of us ! so go and brack the bank and have fun , because if you are trying to have fun and also enjoy yourself forget about how much your going to spend ! Take the children's college fund and spend it

You will have to check the ticket prices based on when you want to go if you're buying individual days. The pricing changes based on how busy certain days are. Kids age 9 and under the ticket prices can be between $5-$10 cheaper than the 10+ ticket. It can be checked at disneyworld.disney.go.com
