Looks like if you are going to get a fun bag this season, it should be in the color of the moment, yellow. I love the MICHAEL Michael Kors Ranger Patent Bag ($298 at Net-A-Porter). I'm in love with patent leather and it looks like a good size to tote around everything you've got!
Here are more yellow bags that I'm eyeing:
JCrew Oslo Bag ($425 at JCrew)
Rebecca Minkoff Nikki Hobo ($600 at Shopbop)
MICHAEL Michael Kors Hudson Soft Large Shoulder Bag ($378 at Shopbop)
Marc by Marc Jacobs Totally Turnlock Faridah Bag ($438 at Shopbop)
Marc by Marc Jacobs Totally Turnlock Heidi Bag ($448 at Shopbop)
