We bought two large bottles of water at concessions, but when we went to the seating area, we were handed cups and told that we could only take in what would fit in the cups (the rest would have to be guzzled or disposed of). Huge venues like Busch stadium have no problem getting people in quickly, so there is definitely a lot of room for improvement regarding the amphitheatre's security screening procedures. It was moving incredibly slowly, and by the time we got to our seats, it was 7:40. The second time, there were still at least 1000 people waiting to get through security about 20 minutes prior to the scheduled start time of 7pm. I found out later from a manager (after we'd already taken our chair back to the car) that they are, in fact, allowed, and she said she would speak to the staff for the future.
They refused to let us bring it in because it was a loveseat style chair, which is not indicated as prohibited on their website (the line worker said it was on the website, but I had a recent screen shot of their regulations, and it wasn't - only seat height was limited, and they didn't measure it because they were automatically disallowing it).
The first time, I brought a loveseat style camp chair in for the lawn. I've gone twice, and both times were a huge headache. I've been attending concerts here for 25 years and have never had an issue until this year.
