People tend to check in during these times:
If you're only taking the elevator for 1 floor, try the stairs.
Don't be late for class or you'll have to walk into a full class! Yikes, how embarrassing!
Protip: there's an escalator too. If you're going to the 3rd floor or less, the elevator's not your best bet. Burn those 30 calories!
Always nice to get a Starbucks before class!
There is a regular door to the far side of the entrance if, like me, you despise revolving doors. I didn't realize this for like a week :P
A place that is very good for Technical Training, and is very well located, in a very easily accessible area.
Never trust technology. Presentation is taking longer than expected. Preparation is the best cure for prevention!
