This tour is worth every single penny - in fact he probably should be charging double what he does! The weather was not entirely on our side the day we went. It's supposed to be dry season and it hasn't really been, so alligator sightings were lower because they weren't congregating as much as they typically do at this time of year. It was also windy, so the ocean mudflats that we kayaked over were murky which made it difficult to see all the sharks and stingrays that were rippling over the surface.
The hike through the everglades was not nearly as scary as I anticipated. Garl made us feel safe, especially his references to knowing who each alligator was by name and the fact that he gives these tours to school kids. He also provided towels to dry off with before getting back into the car.
The 6 mile kayak was tiring due to the windy conditions and tide, but it was worth it because there was no one around. I was apprehensive about the sharks, but we only saw small pups. He does adjust the tours to the participants who come, so do not be worried if a 6 mile kayak is too much, he has alternative kayaking locations.
There are very few actual bathrooms, so be advised to take a potty-break when a bathroom is available!
I would say that you should invest in some items to make this tour even better. Their website recommends some things, but this is what I would recommend to purchase:
1. Polarized sunglasses
2. Quick dry long pants
3. Quick dry long sleeve shirt
4. Waterproof phone pouch
5. Water shoes
6. Sun hat
7. Insulated water bottle
