Hi there,
I found that after a 5000 mile journey to get there, was not so much the port more the island itself. Frankly it would be easier to find the island in "Lost" a total bummer if you come into Houston Bush airport and not Hobby airport. I found the people of the island helpful apart from those at Enterprise car rental. The port building itself was just a 2nd string cruise port, lines for embarking was fine no great hassles whatsoever.
That said if you want that port to grow, it has to have greater transport links with Houston Bush, how can the ONLY car rental location be closed at half day on a Saturday and all day on the Sunday, they say they aren't allowed to drop people off at the cruise terminal???
If you expect a person to pay $210 for a taxi journey plus tip from Houston to the island then you really need to thing are we doing things right on that island. I would say the people I met during my stay on GALVESTON for a couple of days stay prior to the cruise were nice and helpful.
