If it helps - here is my budget for a 4 day Wonder for 5 people without any excursions (my kids are young). I tried to budget high so I would not have any surprises but I have a feeling that I will anyway. It's so easy to spend with the KTTW card! Of course we have traveling expenses since we are driving from NC to Florida. Better start saving now!!
