Me and my wife are in our mid twenties and are stopping at Houston on the last leg of our 2 week break in the US, but as it wasn't our main destination, we only have 48 hours, landing at 6:10pm on Wednesday 25th September and departing 6:20pm on Friday 27th September. Having now gone through the list of attractions I wish I had arrange an extra few days as there is so much to see but maybe next time ;)
I've got a compact SUV (Ford Escape or similar) arranged and I've got a room booked at the Comfort Suites in Webster which should be okay although we can cancel if I find something better but not too fussed about where we stay as we have the car, the only criteria is it's something fairly nice and good value, which the Comfort Suites at Webster fits.
As we don't get in until 6:10pm we probably it'll probably just be dinner then bed on the Wednesday night.
On Thursday I wanted to do the Level 9 tour at Nasa Space Center, but as this is a 4 hour tour starting at 11:45am it probably won't leave room for much else, except exploring the other attractions at Nasa before our tour starts. We have family that live in NW Houston near Cypress so plan to visit them in the evening and go out for dinner with them.
On Friday I was thinking of arranging a late check out, going to Galveston in the morning including going to the oil rig museum. Then head to San Jacinto and check out the battlegrounds, monument and museum for few hours until say 1:30pm. Then pick up the bags at the hotel before going to the airport (George Bush International) for 3pm. My only concern is everything is quite spaced out so would involve a few hours driving on what is already a fairly short day. So perhaps there is a better itinerary for the Friday? Ideally want to do something that is unique to Texas as we're not sure when the next time we're be able to visit will be but we're generally flexible.
Thanks for any thoughts and suggestions you may have.
