Keep feeding 'em, DireIce - help those girls out!
If you enjoy the feeding so much, maybe you should consider building a bigger feeder near a window, so you can watch the bees come and go.
Although, word of caution here if you think about that...bees obviously aren't the only insects that like sugar water, so you might get one or two other uninvited (and probably less friendly) guests from time to time. When I lived in SC, the hornets loved feeding from the hummingbird feeders, and would even chase the birds off (yeah, they were aggressive).
Also, as you've noted already...the more bees, the quicker the sugar water will go. That's a lot of sugar to buy at the grocery store, dude.
