We stayed at Villa #3 (minty green color) while we were at the Pontchartrain Landing. The pictures we saw of the floating villa, prior to our arrival, did the place justice. There may have been some wear and tear by other guests since the pictures were taken.
We were greeted warmly by Shawn, even though the check in office had closed an hour earlier. He was just great to wait for us after closing.
If you decide to rent one of the floating villas, be aware of the fact that you will be staying in a somewhat busy harbor. It wasn't terribly loud at night or anything, but the water around the villa wasn't clean and we saw a lot of cranes and construction activity.
The accomodations were as we expected, and the place was clean and cool - this was pretty important in the first week of August.
Bringing our belongings in and out was a bit of a hassle since there was no quick way to our floating villa without walking a lot of dock space. Unfortunately, we had to move our vehicle quite a ways away from the gang plank too.
Overall, I would recommend this place to travelers.
