Sesame place... What do you pack?

Going Friday with my two boys and some friends with their kids. May get a locker.
My boys are 1 and 3. Both is diapers.
Thinking dressing them in swimsuits and packing...

Extra clothes
Diapers
Wipes
Sippy cups
Small snacks... Gold fish, pretzels, etc
Sunscreen
The usual emergency kit... Band aides, creams, etc
Towel

Taking double stroller

Any recommendation what to pack it in?
Diaper bag or just regular beach bag?
I have the pickle bottom backpack bag so was thinking that, but beach bag is bigger.
Sorry so many questions.
Thanks

Sesame place... What do you pack?

are you going overnight? or just for the day.
You'll need swimsuits, swim diapers, sunblock, and towels.
I didn't bring diaper bag- just brought a changing mat w/ diapers/wipes and put that in my beach bag.
def some dry clothing
as for snacks- you can bring in a tiny personal cooler- to me, it's worth it to fill that w/ juice boxes (some frozen) and water for you 'cause drinks are expensive. I'd also bring some small snacks. The food selection there is the usual fried stuff (chix fingers, fries, etc.)
