Our tropical vacation plans are being derailed because my husband has a conference in Houston the week of spring break. I thought of Galveston as a possible vacation spot as an alternative. I have never been to the Texas coast & have no idea what to expect. Our kids love to swim. We'd love to have dolphin interactions. My husband loves to scuba dive. We'd love a catamarran cruise. I don't know if these things are possible in Galveston at all, let alone in March. We'd want to stay at a family friendly resort with lots of activities. Is this do-able or should we scratch the idea at this time?
