You wont want to miss going to La Villita. It is cheaper to park there and walk to the Alamo, so why you are right there you might as well take a walk throught the "Little Village" and look at the cool shops and the beautiful views. Just behind La Villita is the Riverwalk. The went down took lots of pictures of were Sandra Bullock filmed a movie and waved to all the boats passing by. We then contiued to the Alamo (which seems much nicer this time then in years past) and were even allowed to go into the Daughters of the Republic library where my family and I went to look up some of our ancestor's names.
We had planned to go see the Alamo, but for $10 per person we just decided to skip it this time.
