Can I get by with only two pairs of shoes?

That is the burning question! We are going out of town for a few days, and I've given myself the challenge to only pack two pairs of shoes. This shouldn't be that difficult considering we're going to be on the houseboat the majority of the time. I shouldn't even need shoes! Considering that I can't stand to be barefoot, one pair of flipflops is a given. I keep thinking that between my flops that I'll wear on the houseboat, and then a black pair of flips, that should cover all the bases. But, then I think--what if we go to dinner? Or what if we go here, or there, I may need a different pair of shoes! I can do this. I really can. Two pair and that's it!!
