Amusement parks can be overwhelming, to say the least. With the crowds, rollercoasters, and germs, it may be tricky to determine which items are worth bringing along (after all, you only have two hands). Next time you head to a theme park, beat the heat — and save some money — with these 13 expert-approved items.

1. A Multipurpose Sunscreen Stick

It’s always important to wear (and reapply) sunscreen, especially if you’re spending most of the day outdoors. We recommend this versatile and pocket-sized stick from Neutrogena, which works on your face and body. Buy it now.

2. Boredom-Proof Brain Teasers

Whether you’re driving to the park or waiting in line, these simple toys will keep your child entertained at an affordable price (and they're sold in packs of 12, so there's a variety to choose from). Buy it now. 

3. Walkie-Talkies to Communicate with the Kids

If your children are too young to have a cellphone (but you still want to be able to stay in touch), consider purchasing this set of walkie-talkies. Yes, these devices are not as popular as they used to be, but let’s face it – they sure are efficient (and fun to use, too). Buy it now.

4. A Space-Saving Collapsible Water Bottle

As you make your way through the theme park, it's imperative that you stay hydrated. However, if you want to save money on overpriced bottles of water and beverages, consider bringing your own collapsible bottle (and refill it as needed). Plus, it's BPA-free. Buy it now.

Let’s face it: Theme parks are dirty. Fight off germs with this easily-portable hand sanitizer spray, which kills 99.9 percent of bacteria. It also happens to smell like citrus-vanilla. Buy it now.

6. ...And Wipes, Because You Can Never be Too Prepared

We’ve all been there: You go to the bathroom to wash your hands and the soap dispenser isn’t working.

They’re sold in packs of 210, so you’ll certainly have leftovers. Buy it now.

7. An Eco-Friendly Albeit Adorable Fanny Pack 

In the past, fanny packs have gotten a bad rap. The truth is, though, they’re extremely versatile. This one is made from recycled water bottles, and it’s as chic as it is eco-friendly. Simply throw in your belongings, wear it around your waist, and you're all set. Buy it now.

8. A Set of Disposable Ponchos to Protect You from Unexpected Weather
