Prime Day - Stuff for Parks?

[Princesca]

We have a trip in spring 2023 and I'm scouring Prime deals to see if there's anything of interest. One thing I'm definitely looking for is a small, waterproof backpack or sling bag. Does anyone have any recommendations for that?

Or anything else of use in the parks and on a cruise?

Got this email today, there's a backpack on here that's not a bad price. I do not have this bag.
