I'm hopefully traveling from NYC to MIA for thanksgiving, and I want to bring food with me. I'm only traveling for a few days with little kids and staying at a hotel without a full kitchen, so this is the most practical option, at least for shabbos. The flight is only 3 hours, and I assume another 4 hours of travel time to and from the airport, and then figure another 3 hours in buffer time, so I need a thermos that will keep food frozen for at least 10 hours.
I know that Dan is a big fan of Polar Bear coolers, but those are pretty expensive ($135 for a 48 can cooler, and I would probably need two). Now, to be clear, I'm not saying that Polar Bears are overpriced- I know nothing of them except that they are outside of my budget. That all being said, can someone recommend a good soft cooler that will keep food frozen for at least 10 hours, and is priced at $50 or under? I will be checking it in with the airline, so ideally should also be somewhat heavy duty.
Thanks!
