To all-I appreciate the info. Thanks for posing the question, pnorth!!
Consensus (here and there) is one hour's difference between HOU and IAH to Galveston so I'll go with my first thoughts and choose Hobby. I realize flight times are not as expansive as IAH but I dislike 'road travel' so less of that and I can 'stand' more airport terminal time (sitting in a vehicle vs sitting in bars, restaurants, etc). :grin
Enjoy the evening, all.
