the river walk is always nice, if your into theme parks or have kids there is seaword and six flags, and by the way the san marcos outlets (prime and tanger) are amazing you wont regret going there. there is so many stores and deals youll have a panic attack. if your a young adult and want to party i strongly recommend 6th street in austin. youll find a whole lot of mom and pop shops and food places in austin ( keep austin weird promote local buisness ) and there is always great music shows there. texas in general is fun. houston is also amazing except the traffic can be overwhelming if your not used to it. glaveston and khema are own the coast right next to houston and are great to spend the day at the beach and boardwalk. youll love it!
The AlamoSan Antonio Missions Historical parkDowntown areaMarket Square These are very good areas to visit. Be sure to visit the River Walk. This is in the heart of downtown. Lots of history and shopping and food. Be very care full in the city. you will see a lot of Mexicans and you will see a lot of less desirable people down town.
