Joshua4 - I work at TDS and yes, we are starting to get in alot of summer merchandise... swimsuits, coverups, towels, sandles, bags, etc. We do have more t-shirts now, you might want to take a trip to the store before you leave.
Since kids grow out of t-shirts, I decided to get white pillowcases and have the characters sign that. Our friends are looking after our pets (dog, cat and fish), so I will be bringing extra pillowcases to drop off at Guest services to have them sign for them as thank you gifts. I figure you never outgrow a pillowcase. I still have mine from 30+ years ago!!
