Wow, the first few posts had me really thinking I was the "mean mother on the block" as my kids like to say and a title of which I am very proud

But thankfully I kept reading to find out, yeah, I'm not the only one who limits their kids' spending. I've done spending money several different ways, but my kids have NEVER had more than $100 each for spending regardless of the length of the visit (longest was 11 days) and most often a lot less, and almost always whatever they managed to save themselves.
My favorite way to handle souveniers which I've done on several trips but not so much now that they are older: the deal is if you behave at the park (which has never really been a problem) and don't ask for souveniers at every gift store, Tinkerball or Mickey Mouse or whoever their favorite character was on that given trip, would leave a gift under their pillow each night. I would purchase souveniers such as autograph book, trading pins, tshirt, beach towels, stuffed animals, sippy cups, etc. from
Disney Store or disney.com prior to our trip, have them wrapped and ready to go according to what day we were going to what park. For example, the first night there they might get the autograph book because they would need it the next day. If the first day was at AK, I might leave a AK tshirt for them. The night before Epcot, a passport is a great gift... I was then able to pick out the gifts I felt they "needed" and pay 1/4 of the price for alot of things. I have to say that my kids always found this much more satisfying and loved the surprise. THey spent many dinners talking about what they might find when they got back to the room -- the enjoyed the suspense and surprise element. And, when necessary, I always had the "don't forget that you need to be good (or eat all your dinner or...)" to lean on. THey were always allowed to go into the gift shops and I would keep an eye on what they seemed to really, really want and make sure they got this the last night as a special surprise or I'd just let them pick something out occasionally for being such good kids.
Either way, and this is only my opinion here so no flames please

but a trip to Disney itself should be enough and it is good for kids to know limits and understand that even $10/day or $50/trip is alot of money to be spent on things wanted, not needed.
Have a great trip whatever you decide.
