Fishing Cabins in Arroyo City?

Are there any reasonably-priced fishermen's cabins in Arroyo City? What I found on the Internet were a lot more posh and expensive than what we need. Also, cabins with a lighted pier would be nice. A friend and I would like to do a couple of nights with our kayaks. The launch ramps I saw were a long way away from the town. We could launch from the river bank. We would prefer non-weekend, also.

I lived in Harlingen for 6 months and never fished there! Doh!

Thanks, IslandJim

Here's the one I found. Looks pretty good.
