Well...I live about 15 minutes from the Space Center, so I could help you with that.....but San Antonio and the Alamo are about 3-4 hours down the road depending on traffic.
Might help if ytou put up your schedule.......
Or there are wonderful things called taxi cabs that 9 times out of 10 can get you where you're going.
Im sure most in San Antonio will know where the Alamo is.
