^ This. Also, in my experience, the MI shoe on that Sony camera is a major advantage for travel. I have tried many setups over the years, and staying cable-free is essential in crowded parks.

• Sony ECM-XYST1M Stereo Microphone works great for high-quality ambient sound.
• Sennheiser+MKE+200+Directional+On-Camera+Microphone&linkCode=osi&tag=5422-20" target="_blank" rel="nofollow sponsored">Sennheiser MKE 200 Directional On-Camera Microphone is highly portable and includes wind protection. Both options fit your budget. Basically, they wont block your flip-out screen or require extra batteries.

I was kinda let down by the Sony ECM-G1 Vlogger Shotgun Microphone tbh... felt like I was paying for the shoe connection and not the actual audio quality. If you want better sound for Disney:

• Rode VideoMicro II Ultra-compact Shotgun Microphone sounds much richer but you gotta deal with the cord blocking the screen.
• Deity V-Mic D4 Mini Cardioid Microphone is cheaper but the shock mount feels flimsy. Unfortunately, most affordable mics underperform... might not be worth the bulk.

In my experience, sticking with Sony-branded mics for that specific camera is the way to go because of the Multi-Interface shoe. It avoids the mess of cables that usually gets in the way of the flip-out screen. Over the years, I've tried many different setups, and for something like a trip to Disney, you really want to keep things as light as possible.

• Sony ECM-G1 Vlogger Shotgun Microphone is probably your best bet. It is tiny and specifically designed to work without any external wires or batteries. It pulls power right from the camera body. Since it doesnt have a cable, it wont block your screen at all when you have it flipped out to see yourself.
• Rode VideoMicro II Ultracompact On-camera Shotgun Microphone is the other big contender. It sounds slightly fuller than the Sony G1, but it requires a 3.5mm cable to be plugged into the side. In my experience, that cable can be a bit of a pain when you're moving fast, though the audio quality is excellent for the price. The fuzzy thing you saw is just for wind. Most of these mics come with one. Honestly, the separate mic is almost always better because it focuses the sound on what you are pointing at rather than picking up every single thing in the background. Since you have $150, you could actually get the G1 and still have money left for a faster SD card or an extra battery. Its very simple to use, basically just slide it into the slot on top and tighten it down... no complicated settings needed.

My buddy told me the exact same thing last week. Guess he was right lol.
