Such a great list, and I know I’m repeating things, but:

• Blister bandages
• Moleskin
• Cooling neck gaiters
• Fanny pack
• Hand sanitizer on a carabiner
• Folding fan as a backup (batteries or rechargeable fans can die/have issues)
• Umbrella: for sun and rain
• Ponchos; honestly I’d even bring foul weather gear, lol. It’s totally different living in the area and being at Disney in that weather. And it makes a huge difference. You can just keep on swimming…er, walking, when everyone else seeks shelter.
• Rain gaiters/shoe covers (or sandals/footwear you can get soaking wet)
• Potable charger
• Sunscreen
• Clorox wipes
• Extra ziplock bags
• Packable pack. I gave the sea to summit ultra-sil and it’s awesome, but this looks good too: 4Monster Hiking Pack
