HELP! I need to make a bag decision!

[pezheadmeg]

Having an addiciton to Kipling bags, I go into the luggage store at the mall to see what they have today. They had one I've been looking at on sale, I'm all set to buy it when something tells me I should look to see if they have any Bagalini's, which of course they do. I have the guy put the two on hold so I can think about it over night.

Now it's the basic Bagalini that you guys are all raving about, I was going to buy it anyway. But the Kipling is a smalller sling that can be also carried like a healthy back bag. I can afford both, but my closet and handbag musuem can not. Which one should I buy?

Both are big enough to fit a rain poncho, bottle of water, in addition to everything I would stick in the Disney fanny pack. I just need reassurance as to which one to buy. Is the Bagalini comfortable after a whole day at the parks?
