Well, that's an interesting coincidence. We're currently at Lake San Marino through February before we head more north.
We stayed here last year for the first time and absolutely love it here. Very close to a lot and the Delnor-Wiggins beach is a bike ride away. Very friendly people as well.
I have no idea who the OP is but I can recommend the place where he has a spot available. That's about a $500 discount off the usual Jan, Feb., and March price.
