This is so wierd...we were on the Dream last week and had an odd experience, too. My youngest DD went down the PP once and when she got out she was freaking out itching. She had a welt near her armpit area...actually on her chest. She whined about it and wouldnt stop scratching it. The "medic" checked it and said it didn't look like sea lice, b/c it usually is several little bites all in one area. She had one big welt. So we put ice on it, bought a 2.50 sprite...since the pop station was too far away and I gave her IB for the anti-inflammatory help. This only happened once, although we only did the PP once. HMMMM
