Hi Patkingpin, can you bring a box of ziplocks? Head to the food court and fill the bag up with ice??? It's just ice can't imagine that anyone would have a problem with that. My DH and DD drink SOOO much that I would go broke if I had to keep buying bottles of water all day so I figured I would pick up a big thing of Juice Boxes and bottled water and toss a few in a little cooling bag with some ice each day.
