This really goes for any vacations that you’re driving to. I’ve heard people prepare meals ahead of time, freeze them, bring a crock pot and warm them up in the crock pot. Of course you’d have to have a fridge in your hotel room or constantly refill your cooler up w/ ice each day.
Another tip I received from reading America’s Cheapest family is ~ when they’ve flown .. after arriving they go to the local thrift store, buy a crock pot, go to Wal-mart or whatever and buy canned foods and place them in the crock pot for meals .. no fridge no eating out.
Then they just donated the crock pot to whomever.
