I haven't been impressed with the scrapbooks I've seen at DLR; I'd rather get a basic one from Creative Memories.
The penny books are something like 5 bucks. Not much at all!
Disney has info
here about locations of the penny (and quarter) machines. A penny will cost you 51 cents. DS was going crazy in December about getting just any old penny, but this trip he wasn't so into it, and we got him one (the only one he asked for) from the Tower of Terror shop. He had been incredibly brave in asking to go on the ride, and he was very brave while on it, even though he was scared, and he wanted that TOT pressed penny for his bravery.
We don't buy souvenirs for others (selfish, I suppose), and since I've been a few times this year I know what things I want and would buy... In December I got cold so I bought a sweatshirt and now I'm done with clothing purchases...if you think you'll want something like that for yourself, leave a coat at home and bring about 50 bucks for it.
Pins, I budget about $10 each, though they aren't always that cost. Check out disneypin (or disneypins?) dot com for info on new releases (being sure to check that they are sold at DLR...) and cost, so you have an idea of what you're looking for. The pins are just SO cute when you see them. I'm not normally a collector, and I don't really budget for pins for myself, but I've had to really restrain myself with the pins. So cute!
disneyshopping.com is good to check out, especially the outlet section of the site. I've found good stuff for my son on there, as well as clearance blankets to go along with the $30 blanket we bought at DCA in December! I like shopping there to "pad" the souvenirs I want to get at the parks. I don't nkow if you have kids, but it's a good budget way to get more stuff for them (if you like getting stuff) without breaking the bank entirely.
I've only been to the outlet store once (one of the traveling ones) but we weren't "into" Disney at the time and I didn't buy anything (silly me). We meant to go to the Fullerton store this time, but ran out of souvenir budget money quickly, and didn't get there. But that store can be a good help financially as well!
