HandFan 10000mAh Neck Fan, 360° Rotation Hands Free Portable Fans for your Neck, 48h Lasting Rechargeable Battery Operated Wearable Necklace Personal Cool Fans for Travel/Disney/Sports/Cycling/Hiking

These are insanely good and not too bad. I got mine under $20 on sale.

I enjoy the planning, so for me that's half the fun. It's a much longer phase than the trip it's self so I try to enjoy it, enjoy the process and refinement, more than allow it to be stressful. Sounds like youve got a handle on it, really! Just remember chargers, cables, adapters, headphones for the plane, sunscreen, sunglasses, and rain ponchos. My biggest single protip is high powered neck fan, it makes the Florida humidity and heat significantly more tolerable.
