Wonderful experience, I had a great time, I paid for the Two day pass including for the River Walk, and The Tower of the Americas...Great value!! I would suggest this 2 day package, for especially anyone who's in town for a short period of time, maybe a weekend as well, there's plenty of options for you to choose from, even a 3 day pass/ tickets as well..Saves a good deal of money doing this, buying separate can cost you up to at least 30-40%more depending on what you want... There's 19 total stops to hop on and off, they are All very well listed and marked, just be sure to understand that on Monday some of these attractions are closed, it's not bad or negative, just be aware, for reference.. There's also options for buses as well, there's a regular bus with air conditioning and plenty of room for seating, and I should know, I am 6ft 6inches tall, as well as fun and historical music playing throughout the trip.. There's also a double decker bus as well, it's partially covered in top, but plenty of room as well..The tour lasts about an hour, but it's fun and very interesting and informative too, educational experience for everyone..The costs range from about 29.00up to about 75.00 to depending on what you choose, but remember as well, GREAT VALUE!! Most of these stops you would maybe choose to see and enjoy anyway, and it's cheaper than trying to get to all of them separately or at separate times/days as well...The staff are very nice and fun and friendly, and are ALWAYS willing to help..I even received a message from them saying (( thank you for coming))... That's for real, and that also says they appreciate you, but also remembering you, which is very kind and polite and very important especially in today's life now...I had a blast and great time, and I will also leave a picture or two, thanks again a must do on anyone's trip to San Antonio...
