Sea World is worth the admission price, whether you're young or old, and the Behind the Scenes tour is well worth the extra (when we went) to experience some real learning. Get there when the gates open to sign up for this limited opportunity. You won't be sorry. Fiesta Texas is an amusement park that is VERY HOT most of the time, has some good rides, and very good shows. San Antonio and its famous River Walk must be on your list of things to do. Mexican Food on the River Walk is a definite, La Villata for a sense of the Old Mexican market, a great zoo and botanical gardens, and of course the Alamo...all make for a varied itinerary. The Texas Hill Country allows you to be as active or as inactive as you wish! Enjoy the breeze! This is my backyard!
Quick Tips:
Before you go to the Alamo, catch one of the few IMAX presentations on what happened at the Alamo...it will be very fresh in your mind when you actually tour the missions. Definitely worth the money.
The Hyatt Hill Country Resort is a pampered, relaxing getaway for couples....but NOT at Spring Break or in the Summer. This is when the families are there, so depending on what you want, and who you're bringing...know this!
Best Way To Get Around:
If you are staying outside of San Antonio, you will need a car. If you plan to stay just in San Antonio on the River Walk, you can take a cab from the airport, and then pretty much walk or cab everywhere else...within the city itself. If you want to do SeaWorld or Fiesta Texas, you'll need a car. Your hotel may offer transportation to some of these tourist spots. Ask.
