Hi Latisha!
Great question! The answer depends on the size of the cooler. There is a list of prohibited and/or restricted items compiled on this page:
Restricted Personal Items. One of these items are coolers with or without wheels larger than 24" (61 cm) long x 15" (38 cm) wide x 18" (46 cm) high. As long as the cooler is smaller than the aforementioned size, you will be allowed to bring it in the parks. When my family and I visit, we typically bring a small soft-sided cooler or insulated tote bag with mini-water bottles, can sodas and juice for the kids. I also like to bring a back-pack with chips and other snacks. This has proven to be a real money saver for my family as we typically just spend money on lunch or dinner.
