Sounds like fun. Just be aware that on an airboat the chances of seeing wildlife are slim to zero. The things are extremely noisy scaring wildlife for miles around. They are fast too, further reducing chances of seeing anything, but they are a great thrill ride.
There are options if you want to see birds & gators. There are some good trips with small boats, trailer boats, that may only carry 6 people. A very personal experience.
