I don't have Toms myself, nor does dd, but I remember noticing last May in WDW that there were a ton of Toms. Not as many as Crocs, but enough to stand out as a popular shoe among all of the other standards (teva, keen, etc).
I would recommend probably bringing more than 1 style of shoe for her to wear. Like a pair of toms & a pair of crocs (I personally feel the crocs are my old standby, but toms ARE much cuter and I have been thinking of trying them out - though the 5 year old in me says that I should probably forgo neutral in favor of getting myself a sparkly pair).
Also, I am totally patting myself on the back for getting 32 points in your ADR game! Not the highest score, but still higher than I expected! Congrats to me! lol
I love Maddie's new stuff..have you bought princess dresses from the Disney store before? How do they measure up against what you can buy in the BBB? I have been having an internal debate (mostly because everyone I know is tired of listening) about whether to do the whole castle package at bbb or to buy a dress and just get the hair & makeup at BBB. We did the Castle package last year and it was fantastic, of course, but it would free up some spending money if I came prepared already with a dress...
