does it get packed on certain hours? I just don't like to go when it's full.. I hate people staring

I always check online before I go just to make sure

If you ask the front desk they will provide you with a busy visitors schedule- most of the time it's 4-8 Monday - Thursday

I've just started at Planet, and at least in my experience, it's never terribly crowded. (I suppose the heaviest traffic would be on their Pizza Mondays and Bagel Tuesdays; free food will do that.)
