We have been there in March for 2 weeks, and really enjoy it. For us from Canada it was like an oasis in the middle of the winter;) We had our kayaks and paddle on the river and intercostal water, we had also the bikes, we visited everything around in Miami, had a trip to Keys and travel few times to Everglades.
The cabins are comfortable if you bring some additional mattress, the only thing I can complain about was the restrooms/shower building which need a renovation…
We had our camping gazebo and propane stove to cook and we enjoyed every night a nice fire wood.
If you are allergic to mosquitos and no-see-ums, bring a high DEET insect repellent and some Benadryl spray
