Depends on how well people pack coolers. You put warm beverages in a cooler and fill with ice, do the same with already cooled beverages, which will hold ice longer?
My $.02 is that the guy with the low rating does not know how to pack a cooler to stay cold for long periods of time.
My guess would be to go with an igloo or Coleman. Marine cooler would probably be fine. Keep it in the shade and closed... if you're not going to open it for a long time, you can tape it shut, or something else to help seal of it worries you.
