can anyone recommend a cooler bag/beach bag on wheels or a trolley to take on daytrips out and to the beach to carry all the stuff that a typical UK daytrip takes ie, food, drinks, lotions, jumpers, towels? Now that mine have out grown the buggy I'm carrying all this stuff all day and I feel I need a donkey or a trolley! But don't want a shopping trolley- any ideas? I've tried for 2 day on the interent and can only find wholesalers and USA sellers- Help!
