Okay, a 7 day is the same price as an 8 day till April 26th, it is $179!
Then if your trip is after that, a 7 or 8 day ticket is $209 adult, $179 kid!! Now if you are POSITIVE that you will not be back within the year, then I would save the $30 and not buy AP's (saving more if you have kids because kids AP's are the same price as an adult!) But if there is the slightest chance you might be back, then I would just get an AP for anything over 5 days.
Plus then you get dining discounts and on 5 days or more of food, that would be about $50-$60 for us!!
