Port Aransas
I keep my boat at the Macport Marina and from there I take it to Port Aransas. I use the marina when I'm staying in Port A for a few days. Only had one problem in a year with a bait bucket stolen out of my boat overnight, but that was when I was slipped near the public boat launch. Since then, I have slipped closer to the permanent slips without any problems. The Shark Reef Resort is close, friendly, inexpensive and clean. It runs about $50 per night. Bait can be hard to find if you want to head out in the early mornings so plan ahead as nothing other than the Circle K is open before 6am. Woody's seems to have the best quality bait and most helpful staff.
If there on a weekend, make extra sure that everything is up to regs as you are likely to be stopped by either the CG or Game Wardens.
If staying overnight at the Marina, I believe it is $12 per night.
Do a google search for Port Aransas, and you will find tons of information.
