I think a piece of MK jewely would be great. Along Main Street are so many choices. From inexpensive to some beautiful quality pieces.
Last year I purchased a bracelet at the Contemporary, I think $18. and I still wear it. I get SO MANY compliments on it and it is a favorite of mine. It is a stretch bracelet, though you'd never know it, with small mickey heads iterspersed with words such as BELIEVE LOVE TRUST and with small spacers. You hardly realize it is Mickey until you look close. I guess you can tell I LOVE it.
My husband thought that it was hysterical as I generally choose and purchase precious metal pieces with genuine stones, but I just could not pass it up!
There are REALLY cute charm bracelets (inexpensive yet cute) and charms of every type imaginable that would make a very special gift, especially if you get a few charms of her favorite characters or just start with one, MK and she can add others (hopefuly) in future trips. She can wear it during her stay and have it for the future too!
Whatever you choose for your daughter, have a wonderful time mak'n Memories! Take tons of pix!!!
