There are effectively three things for the price of your ticket; two small museum exhibitions on migration to Texas in the years before WWI and on the Texas Navy of the 1830s and 1840s, plus getting on board the Elissa. The two mini-museums are definitely interesting; I'm always a sucker for the human stories one sees in a migration museum, and the Texas navy is such an obscure an interesting piece of history (for a non-Texan!). As for the Elissa, I have to admit to being a little disappointed, perhaps because I've been on, and sailed on, tall ships before. It's got a lot of functional, non-original features below deck, but in a way that's its strong point showing that it continues to be used. The fact that it's a fully-functional ship is impressive. Before getting on board you should definitely watch the 17 minute video explaining how the Elissa got to Galveston and the huge amount of work, much of it by volunteers, to get it to it's current state. All credit to those involved.
