When is your trip? As far as I know, the only place to get a good selection of characters to choose from is online, but they take a few weeks to arrive. I looked for a certain character one last yr. while we were there to bring back for a friend for her senior trip, and they did not have it - only a few designs in gift shops. I know what you mean, as I have been able to get DS a Mickey Soccer one, and DD a Snow White in the past from the online site. If you have time, you could order those and use your generic ones for other trip expenses like tips, food, souvineers, or give them the minimum($25) on the special cards, and then have the rest of their money(not sure how much you were planning to give them) on generic cards to use after special card. Also, with Christmas coming(if before your trip), maybe other family and friends could use your generic cards to give them spending money if they wanted to do that as a gift.
