In the end we had *one hour* in Galveston to sightsee at our own pace *and* to have lunch. However, we did get to see lots of Houston I would have otherwise missed, and we did stop for 15 minutes or so on the beach front of Galveston which was wild and windy, and we did go on a boat trip and got to see pods of dolphins. It's just a matter of marrying up the programme description to the actuality of the outcome.
