We are leaving in 15 days YIPEEEE!!!!!! We have QSDP. It is me, DH, DS13, and DS 11. We don't really do souvenirs. The trip and pictures are our memories. We don't do any extras like boat rental etc. So how much spending money do I need?
We will be gone 9 days. 2 travel days and 7 days in the parks.
I guess it depends upon whether you think you'll be buying drinks or snacks in the parks, and what you're planning to do for meals. But, if you're talking STRICTLY spending money - i.e. "fun money" - then there really is no minimum.
My 6 year old has been saving his money all year. We'll be there 10 days, and he has $100. I'll give him $10/day of that money. He can spend the $10 each day, or he can choose to save it for one big purchase, or he may choose not to spend it at all (knowing him). For me, it's about him having options.
DD is 15 and has also been saving her money. She has about $250 saved and she'll spend it however she feels she needs to, though I hope she won't spend it all in one place.
I've been stashing away my personal spending money (mad money) for the last year and I have $500 put aside. My plan is to limit myself to a budget of $50/day.
With all of that said, we were there 2 years ago and barely spent anything on "stuff." DD had the most money with her and bought a bunch of little things but, aside from a stuffed Mickey or two, mouse ears for DS and family t-shirts, we didn't buy anything.
So the answer really lies within yourself. If you went with $25/person, then you'd be fine if you're someone who really doesn't see the need to buy "stuff" just cuz you're there.
