Yes.
Be very careful about buying new shoes there and then breaking them in when you are in the parks. Crocs have served us well for years, but I always break them in at home for a couple of months and they do rub blisters initially, but once they take on the shape of your foot they are so comfortable. Take some compeed blister strips with you and keep them in your park bag in case. They also work very well. My feel also tend to swell in the heat and you are putting them through a pounding they don't take on an average day, so you need to keep that in mind.
Sketchers pumps with a cross strap work very well as an additional pair of shoes. If you are doing a lot of walking you might want to alternate the shoes you wear or change them if you take a break and go out again in the evening.
