Well we ate out A LOT, bought tickets to NASA, played a lot of mini golf, went on an airboat ride, kids went to Fun Spot three times I think it was and we bought them armbands every time, two of us went on a helicopter ride (I think that was $30 each), spent a fair amount in Target and Walmart on clothes, DVDs (yes our DVD player does play American ones), CDs etc, bought beer in to drink in the evenings, I went round the shopping malls whilst the others were in Fun Spot (I even bought the outfit I wore to my brothers wedding) and of course petrol/gas. I think we spent over $100 in the NASA gift shop. �1000??? We easily spent twice that!
bablicious - take as much as you can afford - you can always change it when you get back if you don't spend it!
